Hello,
I have a wireless mobile/modem device that uses usbserial driver on
linux. The vendor only provide custom driver for windows. The
usbserial driver works work when the throughput is about 384k. But
when the new modem goes to almost 2Mbps, the linux usbserial driver
can only support to up about 400kbps, whilst on windows it goes up to
2Mbps.
This issue is on boht 2.4.24 and 2.6.6 kernels.
This will impact lots of person because many 3G wireless (CDMA and
UMTD) mobiles/modems use this vendor's chipset.
David Kubicek has rewritten cdc-acm module for 2.6 kernel. It is still
in testing but it seems stable. Patch can be downloaded from
[http://dave.ok.cz/cdc-acm_release/].
