How about running 'lsmod' to confirm your Z recognizes the module? You might need one compiled specific for your hardware. Did you already do that?

lsusb lists nothing. I think I assumed as there was a ttyUSB0 the e220 had been recogniesed.

I did some testing last night with a GPRS Motorola phone that my UBUNTU laptop sees as a generic USB modem. The Z finds it shows it as a device in systeminfo, but I cannot see which device its using again ttyUSB0 cannot be found.

Unfortunatly, I have no idea where to start compiling my own driver fr the Z. Though I have compiled stuff on my laptop for the e220 to make it stable and usable.

Update. I think there is an issue with my USB support. I can mount USB Drives even my mobile phone micro SD. But nothing else. I have tried two mice, both are "seen" in systeminfo, but the icon has a warning triangle as if the driver is not loaded, and the UsbMouse applet does not find a mouse mousedev not found?

Any Ideas what I've messed up?

You didn't say if you did an lsmod, which lists all modules.

Do you mean the Z recognized ttyUSB0? Did you look at /etc/fstab? And which of your Z's are you doing this on? I can say from experience that drivers for one Z won't necessarily work for another model of Z. And the sl5500 is known to not have a USB host controller, so a module alone won't do it on the collie if that's where you are trying.

Capn_Fish only does pdaXrom stuff, but maybe he would know where to get module source code.

Do you have any extra modules installed that have "lite" in their filename?
Look in the cacko feed for this file or similar files with "lite" in their name.
usb-serial-modules-2.4.20_1.23-lite-1_arm.ipk

Any file with "lite" in the filename, are "missing" in cacko lite, and need to be installed if needed.

Sorry if you already know this, it' just a suggestion. smile.gif

hmmm. are you plugging the usb device directly into the Z or using an external hub with a separate power supply? I've seen a few times when a usb device only partly functions if there's not enough power

all with no hub. My aim is to use the e220 0n the move. As it draws little power (less than my phone which works - the phone also charges on usb) and all the lights flash as if the e220 is up I thing (hope) it will work.

OK lsmod with phone in storage mode (no issues)-

lsmod for phone in modem mode :-

bvdd 11136 0

I hope that if I can get the phone to work as a modem then getting the e220 to work woud just be a case of reloading usbserial (which is how it works on UBUNTU)

OK been doing some research, the e220 has some strange driver requirments that needs patching on older kernals so this is not a good buy for a Zaurus. Here's a link to a patch for those of you wanting to run the e220 on an older linux x86 laptop http://oozie.fm.interia.pl/pro/huawei-e220/#WORKAROUND
It may be that someone who knows how to hack this could get it up and running on the Z I can hope ;0)

this says that e220 should work on kernel > 2.6.19 !
so perhaps you should try under modern zaurus distros like Angstrom or Debian !
let's give it a try and tell us about it ! please!!!!!!! wink.gif

No such luck.

It works great on my UBUNTU laptop, but no joy on the Z
