Rather, it uses a TI (Texas Instruments) chipset. While those other chipset manufacturers both make some quality chips, the TI USB-->serial chipset seems to be the de-facto standard in maximum compatibility with the widest array of serial device types. **Q: is it work for Cisco 881router? Thanks** A: I'm not familiar with the 881 product specifically, but it, and older Keyspan models, have worked fine for every other Cisco router or switch that I have worked with over the last 20 years. I've also used it with Adtran and other products using serial connections. **Q: is this compatible with windows 10 out of the box or do drivers need to be downloaded from website? thanks** A: I am continuing to use the 8.1 drivers I downloaded from keyspan on win 10. The zip from keyspan was named Driver-for-USA-19HS-vb5-Windows-8.1.zip but they may have a newer version for win10 but I did not need it. **Q: Are there DOS drivers for this or another usb serial device?** A: Sorry I have no real answer to your question. I am doubtful about DOS drivers for the Keyspan device, and the Tripp Lite/Keyspan web page does not show any drivers at all for the device. Normally Windows and MacOS have built-in compatible drivers, which in my experience work perfectly well, but I suspect there are none for DOS. I believe the cheaper devices that use the Prolific chipset may have DOS drivers. They often are shipped with a mini-CD with drivers and manuals. I have found this impossible to use since all my computers use slot-loading optical drives which cannot accept the mini-CD. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by D***H on July 18, 2025* ### ⭐⭐⭐⭐⭐ Review *by P***. on May 5, 2007* ### ⭐⭐⭐⭐⭐ Review *by D***H on January 21, 2026* ## Frequently Bought Together - Tripp Lite Keyspan High-Speed USB to Serial Adapter, PC & Mac, USB-A to DB9 RS232 Male, 3 Foot / 0.91 Meter Cable, 3-Year Warranty (USA-19HS) - StarTech.com 10' RS232 Serial Null Modem Cable - Null modem cable - DB-9 (F) to DB-9 (F) - 10 ft (SCNM9FF) - Warmstor 6-Pack 9Pin RS232 Serial Cable DB9 Male to Male/Female to Female Mini Gender Changer Adapter Coupler Connector --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/1193036-tripp-lite-keyspan-high-speed-usb-to-serial-adapter-pc](https://www.desertcart.pt/products/1193036-tripp-lite-keyspan-high-speed-usb-to-serial-adapter-pc) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-05-12*
