Description of problem:
After plugging in the USB memory stick, it doesn't work at all. I also cannot
read the contents of /proc/bus/usb/devices for some time (few seconds), and
later it doesn't show the memory stick. Some error messages, which are
reproduced below, are displayed or stored in a log file.

Kernel modules loaded include usb-storage and sd_mod. Attempt to remove sd_mod
results in a segmentation fault.


Version-Release number of selected component (if applicable):
kernel-2.4.20-9

How reproducible:
Always

Steps to Reproduce:
1. Turn on the machine, wait for it to boot.
2. Plug in memory stick.
3. Watch the results.
    

Actual Results:  Error messages, problems with /proc/bus/usb/...

Expected Results:  Memory stick ready to be mounted as /dev/sda1.

Additional info:

Some of error messages:
Apr 21 23:44:58 dhcp03 kernel: usb-uhci.c: interrupt, status 2, frame# 117
Apr 21 23:44:59 dhcp03 kernel: usb_control/bulk_msg: timeout

Machine I use is an old, 440LX chipset-based Pentium II, which uses usb-uhci driver.

Memory stick works OK with Redhat 7.3, and with Redhat 9 using a 2.4.18-3 kernel
(from RH 7.3).
