Depending on the install of Linux you may/may not have the USBSERIAL modules installed as part of the kernel (each motherboard has different USBHUB drivers), assume your USB drivers work (plug in a USB mouse/keyboard/hard drive) will tell you if things are working...

I have done this with two Veer's (on a MAC, with VMWare fusion) on a XP guest, worked like a charm.
