Hi,

Got a number of Redhat Enterprise 3 Workstations which need to be able to read USB pendrives properly.

When plugging in a pendrive nothing happens.

dmesg shows that the system doesnt even seem to pick up that the pen drive gets inserted. Nothing new comes up. I can load the usb-storage module with modprobe fine, lsmod shows its there.

No new sda devices come up in /dev/ so I am completely stumped.
sda1 etc are the local hard disks (would a USB stick try to take the sda1 device tag and hence in this case not work...?)

This happens for all pendrives, so its not the one I'm using thats at fault. Thing is, we had an entry in the /etc/fstab file which had the pendrives working once, this was before a recent kernel update on all the machines. We now run the 2.4.21-27 kernel.

Does anyone have any idea on what I can try, I'm totally at a loss as how to get this working.

Current /etc/fstab looks like so;

LABEL=/ / ext3 defaults 1 1
none /dev/pts devpts gid=5,mode=620 0 0
LABEL=/local /local etx3 defaults 1 2
none /proc proc defaults 0 0
none /dev/shm tmpfs defaults 0 0
/dev/sda2 swap swap defaults 0 0
/dev/cdrom /mnt/cdrom udf,iso9660 noauto,owner,kudzu

Many thanks in advance.

Hi,
Is the uchi_hcd module loaded? or if its in the kernel then check cat "/proc/interrupts". It should have an entry for uhci_hcd. Are other usb devices working properly? I guess hotplug support is also needed. Is it there already?

Hi, thanks for your post. I'll check on the box now.

Nope that module is not loaded. Cant find it in proc/interrupts. Actually come to think of it, on all of these machines we had to use PS/2 adaptors on our USB mice to get them to work ok, the box just wouldnt pick them up or even see them as being plugged in....

I'm getting a lot of people saying that the 2.4 kernel I have is very poop for hotplugging etc and just to update it. Problem is that it HAS to be this Kernel version as no other's work with a piece of software which is needed.
