Problem with USB ASDL modem on Mandriva 2008.1

Tom Nyskelo · 06-06-2008, 11:15 AM

Hi folks,

the thing is that I have a Zhone 6211 usb modem, and it worked very well when I booted Mandriva 2008.1 with Live-CD. Then I installed Mandriva on my hard drive, and it just didn't work. The system didn't recognize the modem, it said something about bad usb descriptor. I tried to plug it into different usb slots, but no luck. When I tried to load two modules (cdc_subnet and cdc_ether), they failed.
I would really appreciate any help,

thanks

since you know it worked.....its just matter of looking at your irq table...your modules and comparing them.

save your current outputs (use root powers pls)

Code:

su
cd /home/yourname/Documents
cat /proc/interrupts > hdirq.txt
lsmod > hdmod.txt
lspci > hdpci.txt

2) reboot and mount your hard drive....if you do not know how is my preferred way pretend your dox on hd partition is /dev/sda2 and is ext3 fs

Code:

su
mkdir /z
mount -t ext3 /dev/sda2 /z
cd /z/home/yourname/Documents
cat /proc/interrupts > liveirq.txt
lsmod > livemod.txt
lspci > livepci.txt

3) now your kernel may already be updated so I will leave that aside.

4) if irq lists are the same we can ignore...but always insert usb modem into the same jack pls

5) now compare your modules and pci devices and see if there are differences

I like to use a mdv app called xxdiff.....you navigate to the Documents folder and run
xxdiff file1 file2 and it gives you nice colours

hopefully there is more than just the modules you named otherwise I have wasted your time

Hello, aus9!
Thanks for trying to help me!

But I'll only be able to get to that PC tomorrow, and then I'll post the results.

Thanks again,
