MUSB driver on AM3352 dropping USB packets

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I have been investigating communication issues with iPads. When the system is busy it seems that the musb driver is silently dropping occasional packets. I have a usbmon trace that does not show the packet and I have a trace from a hardware USB analyser that does show the packet. So the device is correctly sending the packet, it is even being ACKed, but it is not passed up to the application. The packet is a bulk transfer packet of 20 bytes. Can anyone please give me pointers to where to go looking for the problem? The syslog shows nothing relevant.

Thanks,
Andrew
