what chipset is this?

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.

is it work for Cisco 881router? Thanks

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.

is this compatible with windows 10 out of the box or do drivers need to be downloaded from website? thanks

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.

Are there DOS drivers for this or another usb serial device?

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.
