I have a graphics workstation based around an Intel D975XBX2 motherboard with
quad core processor and 3GB RAM. USB host controllers are Intel 82801G (ICH7
Family). Only one of the five host controllers is connected to the 6 external
ports. This is listed as a USB2 enhanced host controller.
I am experiencing problems with a Sandisk ImageMate 12 in 1 card reader
modelSDDR-89 V4 and a Western Digital 2TB external mirror raid drive, both
USB2 peripherals.
Both were bought at the same time and shortly after I had installed XP SP3.
Plug and play installation of the WD drive went through most of the automated
process before indicating that the drevice had not installed correctly. No
external drive was recognised. The computer froze completely while trying to
install the Sandisk card reader.
I scanned the system and identified some old drivers. All relevant hardware
and XP drivers were checked and updated where necessary. BIOS was also out of
date so this was also brought up to date. No change.
All the USB controllers were removed via the device manager and the system
allowed to reinstall them - no change.
The USB root hub has been checked. 8 ports are available in total of which 6
are actually physically available. An External hub is connected to one port
and supports the keyboard and mouse. This draws 500mA. A second port connects
to a printer switch and draws from 2 to 10mA in operation. Each port is rated
at 500mA and there is no indication that too much is being drawn on any
particular port.
The operating system was rolled back to SP2 and the checks above repeated.
Now the Sandisk drive installs but it can take up to 5 minutes for the
operating system to recognise the four additional 'drives'. It then tries to
autoplay, even with no card in the reader. This does not cancel and can go on
for another 5 minutes.
The WD drive still does not install.
I have the same problems on a laptop, also running XP. I got the WD drive to
come up on this machine once when rolled back to SP2 but it disappeared after
rebooting and has never been seen again. This machine also uses Intel host
controllers but a slightly older chipset.
All the external hardware works fine under Vista (and fast too). Microsoft
say it's a hardware problem.
I am out of ideas.
