USB Device Not Recognized? Troubleshooting USB Extenders and KVM Systems
A USB device may work normally when connected directly to a computer but stop working after a USB extender or KVM system is added.

TAA is a U.S. trade-agreement law governing product eligibility in certain government procurements. It is not a general customs import rule.
When TAA applies, the relevant FAR clause generally requires U.S.-made or designated-country end products, subject to the solicitation and applicable exceptions.
A product that does not meet the country-of-origin requirement may not qualify for the procurement, even if its functionality, price, and delivery schedule meet the project needs.
This does not necessarily mean the product cannot be imported or sold in the U.S. commercial market. Importation, product safety, and other regulatory requirements must be evaluated separately. TAA concerns eligibility under covered government procurements.
The fastest initial check is to confirm three things:
Does this procurement require TAA compliance?
Does the country of origin of the actual delivered product qualify?
Do the model, version, accessories, and documentation match?
It confirms whether a product's country of origin meets the requirements of a covered U.S. government procurement.

TAA is short for the Trade Agreements Act of 1979. For procurements covered by applicable trade agreements, qualifying products from designated countries may receive the same treatment as U.S.-made products.
An end product is the product the government actually purchases under the contract—for example, an HDMI extender, KVM switch, network switch, or separately listed HDMI cable.
Simply put, TAA looks at what end product is being acquired and whether its country of origin meets the applicable procurement requirement.
No. The solicitation and contract clauses should always be checked.

TAA applicability depends on the procurement rules, value, agency, product or service category, contract clauses, and exceptions. Different procurements from the same government agency may have different requirements.
When receiving a government RFQ, first check:
A product used in one government project is not automatically acceptable for the next.
The first step is always to check the solicitation. Do not determine TAA applicability based only on the agency or project type.


To qualify as a U.S.-made or designated-country end product under the applicable rules, an article generally must satisfy one of the following:
TAA does not require every component to come from a designated country.
The focus is the country of origin of the completed end product.
Substantial transformation is a key standard for determining product country of origin.

The key question is whether manufacturing or processing results in a new and different article with a different name, character, or use.
Because the determination is fact-specific, use the following table only as an initial screening guide.
An HDMI extender uses components or a finished functional assembly from a non-designated country and only undergoes the following work in Taiwan:
Those activities alone may not be enough to establish Taiwan as the country of origin under the substantial-transformation test.
Chips, PCBs, connectors, and unfinished modules enter Taiwan, and the following manufacturing steps are performed there:
The process creates a complete device with HDMI signal-extension functionality.
Depending on the full facts, this manufacturing may support a finding of substantial transformation in Taiwan.
Simple processing is generally not enough by itself. The key question is whether the local manufacturing actually creates the new finished product and its functional identity.
A TAA-eligible product does not have to be manufactured in the United States. Products from qualifying designated countries may also meet the country-of-origin requirement.

Examples commonly encountered in AV, IT, and electronics procurement include:
※This table highlights countries commonly encountered in AV and IT procurement and is not a complete list. Designated-country status should be checked against the latest FAR and GSA information.
Taiwan is currently a TAA-designated country under the WTO GPA category.

It is also a major manufacturing base for semiconductor, electronics, ICT, Pro AV, networking, and surveillance supply chains.
A product wholly manufactured in Taiwan—or substantially transformed there from materials sourced from multiple countries—may qualify as a Taiwan-origin product under the applicable standard.
The same general method applies to Japan, South Korea, Germany, Singapore, and other designated countries.
Country of origin depends on where the relevant manufacturing or substantial transformation occurs—not simply on the invoice, shipping location, or packaging.

Consider this example:
An HDMI extender completes its principal manufacturing process in a non-designated country and already has its full signal-extension function before entering Taiwan.
A Taiwan company changes the outer box and manual, applies its own brand label, performs basic testing, issues the invoice, and exports the product to the United States.
Routing the product through Taiwan alone does not make Taiwan the country of origin.
The key question remains:
Did the processing performed in Taiwan create a new and different article with a different name, character, or use?

Yes.
Using components from non-designated countries does not automatically disqualify the finished product.
A useful initial check is:
Did parts or unfinished assemblies enter the country, or was the functional finished product already complete?
Did the local manufacturing actually create the new finished product?
Labels should reflect the actual country of origin and should not be used as a substitute for manufacturing facts.
Knowingly representing a nonqualifying product to the U.S. government as TAA compliant can affect bidding, delivery, and acceptance and, depending on the facts, may create False Claims Act exposure.

TAA compliance is not necessarily proven by a single permanent government-issued certificate covering every product and procurement.
For procurement due diligence, the key question is:
Does the documentation match the exact model, version, accessories, and manufacturing configuration currently being delivered?
A practical supplier document should make it easy to identify the manufacturer, exact model, stated country of origin, applicable product or hardware version, relevant manufacturing location, document date, and issuer.
Review the solicitation, RFQ, or contract to determine:
Do not verify only the brand name or product series.
Check:
Products in the same family may be manufactured at different facilities and may have different countries of origin.
Manufacturing arrangements can change.
If a manufacturer changes the production facility, OEM/ODM partner, PCB, hardware version, or major production process, a previous country-of-origin statement may need to be reviewed again.
Procurement teams should confirm that the exact model, manufacturing location, applicable version, and document date still match the current product.
Long-term contracts and repeat purchases should be rechecked periodically rather than treating an old document as permanently valid.
Potential consequences may include loss of bid eligibility, delivery or acceptance delays, contractual remedies, and—in cases involving knowingly false representations—civil liability.

A nonqualifying product or unclear country-of-origin documentation may affect the procurement result.
Contractors are expected to deliver products that meet the applicable contract requirements.
If the delivered model, manufacturing location, or country of origin differs from the submitted information, the government may require clarification, corrective action, replacement, or other contractual remedies.
The False Claims Act can impose liability for knowingly submitting a false claim or certain material false statements related to a government claim.
Potential liability can include civil penalties and three times the damages sustained by the Government.
The U.S. Department of Justice has published multiple settlements involving TAA-related allegations.
Both are settlement examples and should not be described as court findings proving every allegation.

In 2025, Vanco announced a line of HDMI, USB-A-to-USB-C, and USB-C-to-USB-C cables marketed as TAA compliant. The company stated that the TAA cable line was made in Laos.
This example shows that TAA-related product checks can extend beyond matrix switches, extenders, KVM products, and network switches.
If a cable is a separately acquired and delivered item under a TAA-covered procurement, buyers may also need to verify:
Low price does not make country of origin irrelevant when the item is a covered contract deliverable.
This manufacturer example is included only to illustrate a market approach to product and documentation management. It does not mean SC&T has verified or endorsed the product's TAA status, and it does not replace the applicable solicitation, contract terms, or government determination.
According to SC&T's current internal product information, more than 95% of its products can meet TAA-related country-of-origin requirements.
Eligibility still needs to be checked against the exact model number, hardware revision, manufacturing location, kit accessories, and procurement requirements.
For government projects requiring TAA documentation, provide SC&T with the exact models and document requirements so we can supply current country-of-origin and product information for review.

Government projects may address supply-chain and cybersecurity concerns, but TAA itself primarily addresses qualifying product origin under covered government procurement rules.
A TAA review does not have to begin with pages of regulatory language.
Procurement professionals and system integrators can start with four questions:
If any point is unclear, confirm it with the supplier, government project contact, Contracting Officer, qualified legal counsel, or appropriate government authority before assuming compliance.

This article provides general information on TAA, U.S. government procurement, and product country of origin. It is not legal advice, contract interpretation, government certification, or a compliance guarantee for any product.
Whether TAA applies and whether an individual product qualifies can depend on the contracting agency, solicitation, contract clauses, product model, hardware version, manufacturing location, manufacturing process, and delivered configuration.
Regulations, designated-country lists, and government procurement requirements may change.
Readers should not rely solely on this article when making bid, procurement, country-of-origin, or compliance representations.
For a specific procurement, refer to the latest solicitation, contract terms, and official regulations. Where necessary, consult the Contracting Officer, qualified legal counsel, or appropriate government authority.
Third-party websites, manufacturer information, and product examples are provided for reference only and do not constitute SC&T certification, guarantee, or endorsement of any product or compliance statement.

AV requirements in a medical simulation center go beyond recording a training session. In addition to room camera feeds and audio, a session may require recording patient vital signs, ultrasound images, or displays from other equipment. Some content may need to be sent to a control room or observation area for live viewing and later used during debriefing.
PoE, PoE+, and PoE++ all carry network data and DC power over an Ethernet cable. The main difference is the amount of power they can deliver. Basic PoE works for many low-power devices, such as IP phones and some PoE IP cameras. PoE+ provides more power and is commonly used for PTZ cameras and wireless access points. PoE++ uses IEEE 802.3bt Type 3 or Type 4 to power network devices with higher power requirements.
