Win XP Pro

When I shut down the computer then restart, the external Seagate drive letter may or may not show up, and the wireless adapter driver disappears from the Network Adapter list (it also sometimes disappears during usage or suddenly shows up yellowed out)
If I try to reinstall the wireless adapter, Windows shoehorns in and installs it incorrectly as an USB device where it won't function.
The only way I've found to get the external drive letter to reappear and for the adapter to install properly is by:
Removing the wireless adapter from programs.
Shut down the computer
Unplug the external drive's USB cable and electrical connection.
Unplug the wireless USB adapter connection.
Unplug the computer and wait for at least 10 minutes.
I know this sounds crazy, but everything then installs and works properly until I shut down then on restart I'm back at square one again.
If I omit unplugging the computer, then as soon as it boots up, Windows reinstalls the wireless driver back under USB devices where it won't operate.
No virus present, no spyware, run chkdsk and scannow, tried a repair but no luck.Needless to say, this is driving me crazy.

Here's some inherent problems with usb and why contrary to popular belief, it had real issues.

Usb devices and the bus they run off of draw power from the motherboard, this power is limited by design to ~ 200milliamps total, next it's a shared resource, no matter how many channels it says you have they are shared. The biggest issue for me is that all usb is handled by the system/cpu. Usb is rejected for video capture due to it's weaknesses. Try to isolate your problem by eliminating some devices and see if it's a resource conflict or a power issue. Whoever claimed that you could hook up a 132 devices(or whatever) should have been shot. A powered hub helps.

Rarely I see a driver issue and that's when someone tries to load one, XP sp2 has it's own and that's one mess that MS has handled well.

No. Try not. Do... or do not. There is no try.

I think I would take a look in Event Viewer, look for clues as to what the problem is and possibly how to correct it. I would look for 3-5 errors that approximate times when things go wrong on the system. I would post the results back here.

Thanks, and of course to be perverse, nothing has occurred since I posted.

Whenever I'd respond to USB questions. I always gave the standard responses. Some times they worked and other time, not. Then my USB went bananas. Besides using an enclosure that has it's own power supply, as DaChew mentions, The simplest fix is an add-on USB card. It fixed all my problems in the 5 mins. it took to install it, plus they're cheap. Even USB Pcmcia cards are reasonably priced
