zaurus usb dmesg error, new to zaurus, and hey first post. hi

erikmallinson · 06-30-2005, 01:20 AM

I just purchased a sl5500, installed openzaurus 3.5.3 (gpe), and use ubuntu. After installation I cannot reach the zaurus via usb - on dmesg I get:

Code:

usb 2-1: new full speed USB device using uhci_hcd and address 7
usb 2-1: device descriptor read/64, error -71
usb 2-1: device descriptor read/64, error -71

where the address is cumulative every time i start the zaurus in the cradle. i'm ok with linux in general but new to the z and i'm really banging my head on my desk at this point.

basically i feel stranded. i got qtopia installed on linux, flashed openzaurus to the pda and now i can't connect my pc to the pda. I don't own a CF reader either, or I suppose this would be a moot point.

Can someone please get me up to date on this issue? Is it a known bug, something I can easily fix, something I can not easily fix, etc?

ps - i really admired y'all at linux world boston.

edit: I guess I should describe my goals.
1. to be able to transfer files from pc to pda (erm, i think i want to install opie instead).
2. to sync the data to my desktop pc.
3. to sync the data with evolution

Welcome to LQ !!!!!!!

I had a compaq Ipaq a few years ago, similar setup to yours, but ended up bluetoothing things accross as I couldn't seem to find a way to connect. Don't give up though. I was new to linux then, and didn't really know what I was doing.

Cheers

here are some links to the possible problem. Since it's not reading the usb device at all i'm ruling out that it can connect via anything (ftp, ssh) and that it's a bigger problem. When I dropped the specific error # and searched for "device descriptor read/64, error list" to see what the number reffered to I suddenly found that specific error message.

Basically from what I understand is that there was a change with linux-kernel 2.6.x with usb and I should set the usbcore.ko to

Code:

old_scheme_first=y

. Except somehow the permissions aren't correct for editing this file, so it's not possible to change it. In the mepis forum there is another solution commented that I could just put the setting in modprobe.conf, but I cannot seem to find the file on my installation.

There is also a script on the Hull LUG forum that fixed this for some but i'm not really into just blindly trying it, for I'd prefer to not bork my desktop OS if possible. I've tried searching for this as a Ubuntu problem, but i've not seen anything so far.

Here's the links:

... aikidoist, thanks for the encouragement, i'll keep trying... The main problem is that I don't have any accessories for the pda yet. It seems that I either read selectively or didn't find the whole slew of pages about zaurus problems when I was shopping! I was sort of expecting what many have, that since it was a linux pda that it would talk to my linux box happily and immediately! To think, aside from my palm os pda dying my biggest problem was that it wouldn't keep the categories when it synced to evolution! Those were the days.

Anyway, anyone else have similar problems? This possible solution seems a lot more general than Zaurus connectivity.

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)

Good luck!

Zaurus User Group http://www.zaurususergroup.org/ is an absolute "must bookmark" if you have a zaurus. I have found many of the answers I needed on there.

I to am trying to sync a ipaq. I have not succeeded yet but My computer will find my Ipaq after I setup the connection in minicom -os make sure it is set to /dev/ttyUSB0 At least it sees my ipaq so I am heading in the right direction that is in Fedora 9

The oesf forums have information and help for ipaq's as well.
