Zaurus SL-5500 USB Problem


Hi all,

I just purchased a Sharp Zaurus SL-5500 and am running OpenZaurus/GPE on it. I love the device, but ran into problems when I wanted to connect it to my computer. I am following the directions on the OZ website, but when I put the Zaurus in the cradle, the computer doesn't recognize it. lsusb gives me nothing, and dmesg reports:

Code:
ohci_hcd 0000:00:02.0: wakeup
usb 1-1: new full speed USB device using ohci_hcd and address 33
usb 1-1: device descriptor read/64, error -110
usb 1-1: device descriptor read/64, error -110
usb 1-1: new full speed USB device using ohci_hcd and address 34
usb 1-1: device descriptor read/64, error -110
usb 1-1: device descriptor read/64, error -110
I'm running Ubuntu 5.04 (Hoary), with the stock kernel (2.6.10-5-386). lsmod |grep usb gives:

Code:
usb_storage            64064  0 
scsi_mod              119936  2 sd_mod,usb_storage
usbnet                 25736  0 
mii                     4736  1 usbnet
qcamvc_usb              6784  0 
qcamvc                 20612  1 qcamvc_usb
usbcore               107384  7 ehci_hcd,usb_storage,usbnet,qcamvc_usb,ohci_hcd,ndiswrapper
ide_core              118988  5 usb_storage,ide_cd,ide_generic,ide_disk,amd74xx
(I believe I probably loaded usbnet manually to see if it would help the problem).

Any suggestions?

I just put GPE on an older iPaq I had lying around and found an error in my 'dmesg' Googling it, I came up with this thread. As I also run ubuntu, I guessed that I would run into the same issue recompiling my kernel as you mentioned. (Although I have to ask, did you try 'sudo vim /usr/src/linux/thefilethatIwanttoedit.x' ?)

I tried a bunch of different combinations of turning my ipaq on and off and plugging it in at different stages in between, but I got nothing. On a whim, I tried a different USB port. To my amazement, it worked. So the answer to your question? I wish I knew. Maybe try different USB ports, because with some motherboard manufacturers it makes a difference, especially under linux.

Just for the record, here's the relevant portion of my dmesg :

Code:
jedediah@hoju:~$ dmesg | grep -i usb
usbcore: registered new driver usbfs
usbcore: registered new driver hub
ohci_hcd: 2004 Nov 08 USB 1.1 'Open' Host Controller (OHCI) Driver (PCI)

usb0: register usbnet at usb-0000:00:02.0-1, Linux Device
usbcore: registered new driver usbnet
Good luck!
