## Questions & Answers

**Q: what chipset is this?**
A: I'm sure the OP either already has the answer for this, or has moved on...but I wanted to answer this question for anyone else that might want to know (because it took me quite a while to research all the information for myself).This device does not use either of the two main manufacturer's chipsets (it's not an FTDI nor a Prolific).  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.
