I'm trying to develop an driver for the TUSB3410-Serial To USB-Converter-IC. But I'm still having problems developing the firmware for the IC. I always get the following message:
usb-uhci.c: interrupt, status 2, frame# 962
Where 962 can be any number.
I'd don't know what's the reason for this message. I've search the net for an explaination, but nearly all sites where this message appears are bugreports. Is there any list with the interrupt status codes of the USB controller? Or can somebody give me a hint what I am doing wrong?
I've attached a logfile with the messages generated by the usb-module. I'll explain the way the TUSB3410-IC is working a little bit, so you understand why there are two device connects:
1. The device connects to the USB with a predefined bootloader (in ROM).
2. It wait's for its firmware being sent to OEP1
3. It disconnects from USB by disabling the pullup.
4. My firmware starts, initializes the registers and the connects to the USB again.
And here I'm getting the interrupt message.
BTW: All the descriptors listed by the usb module are correct(=as defined in my firmware)!
If it helps you I can also post the firmware.
Thank you in advance,
Hermann Kraus
