what's the state of USB in 5.2? I'm using an old DFI K-6 mb that has a VIA 83C572 usb controller to do usb driver development with a Cypress FX2 eval board. The whole thing works fine under 4.9, but the same setup under 5.2 has some problems. it can see the usb chip, can detect the fx2 board and attaches the ugen driver. it will not complete any operations, however. i'm using ezdownload to load test firmware. it works under 4.9 but under 5.2 it simply hangs on the first operation with the target. the system doesn't freeze, just the ezdownload. in addition, ezdownload cannot be aborted. also, the 5.2 usb system doesn't seem to be able to detect new devices. after reboot (no operations pending), i see the system has recognized the device, i remove it, the system notices that its gone, i reinsert the device, but nothing happens. i would use 4.9, except that the driver i will be writing must eventually run in an amd64 environment. is anybody familiar with the 5.2 usb code, and has some information about these problems? thanks, ron.
