We are currently using generic usbserial driver. It works but not very well. The Nokia phone is apparently not compabible with the existing ACM driver. When we plug it in, the ACM doesn't claim it. However, another vendor's phone would work with ACM.
Because Nokia is not release the linux driver (or patch) yet, we'd like to see if anyone is willing to write a driver for this device. If possible, I will go to my senior management for finacial support the development of the driver. One thing I don't know is if we need the Nokia USB spec (we don't have it).
Thanks,

Hi Simon,
I work for a major wireless equipment provider. We need a linux USB driver
for one of Nokia's 3G mobile phones. If you are interested in this contract job, please let me know. The device detail follows:
T: Bus=01 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 5 Spd=12 MxCh= 0 D: Ver= 1.10 Cls=02(comm.) Sub=00 Prot=00 MxPS=64 #Cfgs= 1 P: Vendor=0421 ProdID=040e Rev= 1.60 S: Manufacturer=Nokia S: Product=Nokia 6651 C:* #Ifs=11 Cfg#= 1 Atr=e0 MxPwr= 8mA
I thought that have seen such device before and I looked through my emails. Yes, I had already discussed some issues with a guy from Nokia about a similar product. It was the Nokia 6650 with Id 0421:0401, but the interfaces are the same.
I: If#= 0 Alt= 0 #EPs= 0 Cls=02(comm.) Sub=08 Prot=01 Driver=(none) I: If#= 1 Alt= 0 #EPs= 1 Cls=02(comm.) Sub=02 Prot=05 Driver=(none) E: Ad=81(I) Atr=03(Int.)

He stated that a patched acm driver whould claim the two interfaces. I can't find his patch, but a look through the USB specs will help to see if Nokia has followed it.

These three are OBEX transports and I proposed that he should write a patch for an USB transport layer for OpenOBEX. But I never got any further code from him.
However from my email archive I see that it was a private discussion, so there is no mailing list to look at. What do you expect from the Linux driver?
Regards
Marcel
