Win XP (up-to-date)

problem:  I have 2 usb ports on the front of my tower.  I used both for popping in a flash drive successfully for a year.  then my wife's flash drive started to completely hang win xp upon insertion into port.  my flash drive worked fine.  upon problem, a reboot is only remedy (with flash drive in place).  CTRL-ALT-Delete is dead. this problem  seemed to manifest in 1 or the other port, but not both. Later it involved both ports.  Recently, the problem surfaced with my flash drive, and eventually manifested in both ports.  I sought help on this site at this time.  I read about "unchecking 'power management' " for usb root hub.  indeed, boxes were checked to my surprise.  i unchecked them.  the problem disappeared until next bootup.  problem persisted even though 'power management' has never shown up 'checked' again.    next i uninstalled 'usb root hub' and 'usb mass storage device' drivers. (BTW, my PC shows 7 of the former and 2 of the latter, together with other "intel enhanced host controllers', etc. ) i forced win xp to reinstall these for me.  problem disappeared for one to three boot cycles; then returned.  repeated this uninstalling  the 'usb mass storage' drivers that i am almost certain correspond to these 2 ports.  forced a reinstall for these 2 drivers.  problem resolved for 1 to 3 boot cycles and returned.  tried this again one or two times.  same result.  i went to site: and found a 2003 dated version offering of the same driver i had been replacing associated with the 2 'usb storage device' listings.  it is file:  USBSTOR.sys.  my original was dated 2001.  i saved my driver and replaced it in my 'C:\WINDOWS\system32\drivers' folder with the downloaded version by same name.  again, i uninstalled the 2 and forced win xp to reinstall - presumably picking up the downloaded new driver.  this resolved the problem for enough boot cycles (3 to 5)  that i thought the problem was solved.  now it has returned.  my flash drive is a typical attache brand i don't know what else to try.  any help will be appreciated.  thanks.   william
