OHCI / EHCI randomly crashes

Open tuxuser opened this issue 13 years ago • 6 comments

There are reports where the crash appears even if no USB device is plugged..

stackdump, reported by "BioHazard". He got it when attaching a fat32 USB Stick right from boot. When he attached FAT32 AFTER "usb_init()" the device didn't get enumerated - so it didn't crash.

And here's the actual problem I was talking about - related to tinyehci / usb init!

  • usb init
    • Initialising USB EHCI... Initialising EHCI bus 0 at 0xea003000 Initialising EHCI bus 1 at 0xea005000 EHCI bus 1 port 4: low speed, releasing to OHCI
    • Initialising USB OHCI... USB bus 0 device 1: vendor 0000 product 0000 class 09: USB Hub USB bus 1 device 1: vendor 0000 product 0000 class 09: USB Hub USB: New device connected to bus 1 hub 1 port 4 USB bus 1 device 2: vendor 045E product 02A9 class FF: Xbox 360 Controller
    • Xenos FB with 148x41 (1280x720) at 0x9e000000 initialized.
