Thanks Barb. Power management was already disabled on all USB hubs but I did
switch the adapter over to a different port. I'll see how it goes after a
few boot cycles.
Meanwhile, the computer is an HP m1280n. USB is onboard, both 2.0 and 1.1
controllers, with 6 (combination) ports installed plus a 9in1 memory card
reader. Four USB ports are always in use but the USB wireless adapter is
usually the only USB 2 device connected. Hmmm, interestingly it isn't
reporting any power requirements.
