I have a
http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=2893289&CatId=464
uses mos7720 chip.
they have a linux driver on the site but it wont work on newer 2.6 kernels it uses SLAB_ATOMIC etc. needs updating.
The 2.6 kernel has this driver and i have seen some activity 6 months ago on it but nothing recent.
This driver for me does not work when i try to cat /dev/ttyUSB2
it fails and when i try to run
statserial /dev/ttyUSB2
statserial: TIOCMGET failed: Invalid argument
debugging seems to get me a bit lost one thing i notice is that the interrupt handeler never gets turned off. Other serial usb modules do remove the interrupt on close.
Was hoping someone had this hardware and had tested to see if it is just me.

We are always looking for testers. Can you recompile with CONFIG_USB_DEBUG,
provide a log and do an strace of your applications?

Oliver, Thanks for the reply.
I would be glad to help.. I hope the format of this information is what you expect if not please let me know.

Strace Log

This is the most recent mos7720.c from
/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
But it is compiled against my 2.6.22.13-0.3 kernel if thats a problem I can run this under another kernel but it did not seem as if anything had changed that would be a problem in this kernel.
I have a few mods I have made trying to track down whats going on mostly just some extra printk's and a fix to turn off the interrupt urb upon closing the device.
