Hello I am in the process of writing firmware for an USB device based on an 8051 core. I am testing it against linux kernel driver. I am submitting an urb to the device via a linux kernel modul, and I get no response. The urb eventually times out. Via debug FS I can see that the urb is indeed submitted. I suspect the firmware to be responsible for this.
I would like to exclude the linux test driver owever, and wonder if there is a cheap way to monitor what is happening on the USB bus itself. USB protocol analyzer start at 1100 USD which is more than I would be willing to invest.
