Hi, I'm working on am33xx based board with 2 USB hosts. I'm using 3.9 kernel + patches from Daniel Mack (http://www.mail-archive.com/linux-usb@xxxxxxxxxxxxxxx/msg19509.html). With patch below I can have both USB ports working on am33xx board with one small problem. When connect 2 usb keys to both ports all of them are correctly enumerated and mounted. But when disconnect both of them then first one disconnected properly but second one fails with warning: [ 103.685497] musb_stage0_irq 791: unhandled DISCONNECT transition a_wait_bcon) I was looking at /sys to check what is current mode and when unplug first usb then mode for both is changed to a_wait_bcon and this is the reason why device isn't disconnected. Any ideas what to check or is there any existing fix for that?
