FWIW, i've been running a VP2 with serial datalogger and a serial2usb dongle for something like 10 years now. I started with a Shuttle mini-pc that had serial ports and switched to a little arm box that just has USB. Never had an issue with the serial2usb from day one. Works great. You basically just want to make sure you get the right chipset in the adaptor. Anything with the PL2303 definitely works. Both mine have that chipset, and they were picked up years apart from different suppliers, so they used to be pretty much what you always got. I haven't looked in years to know if that's still the case. I'm running on a Seagate Dockstar (a 128MB RAM version of the original PogoPlug) with a Seagate laptop drive plugged in, and you can see the serial adaptor available in the lsusb output below. root@debian:~# lsusb Bus 001 Device 002: ID 05e3:0608 Genesys Logic, Inc.
