Hello, We are developing a VoIP enabled WiFI mobile handset using PXA255 running Triton Linux 2.6.10.We have enabled the RNDIS gadget in the kernel for the Ethernet over USB functionality When the handset is connected to the USB port of Windows XP host, the USB peripheral will enumerate to the host as an Ethernet device . However the network connectivity is lost frequently with the message "UDC:USB Reset" in the device side when VoIP activity is happening or the host is used for browsing internet/download. We are using the standard RNDIS drivers bundled with the XP distribution.
We get the following error when we connect handset to the PC through USB. "This device cannot start. (Code 10)" (1) If the connection (ping between PC and handset through USB) breaks, most of the time the connection will come after unplugging and re-inserting the mobile handest to PC. (2) If we repeat this, ultimately we will reach a point in which connection will not recover by unplug and re-insert method. In this case the Windows XP machine will have to be restarted. (3) There are cases that USB Gadget is not up and working well even after the above step . In many cases the network property setting for handset in the XP machine will hang. If it hangs, we will have to restart the PC. 4)Is there any patch/workaround for this? 5)Does back porting from 2.6.14 works? 6)Any idea whether alrernate drivers available for windows host like ndissub.sys/Bahia are stable . http://www.smallpig.org/ndisusb/. 7)The same functionality is available for PXA 255 based pda's available like Zaurus,gumstix,ipaq,yopy .Does thay use the same drivers in Windows XP distribution and the device side stack.
