I've caused a deadlock with multiple bus powered USB hubs (mostly extension cables) connected at once. It just suddenly stopped at "usb 4-2.4.4.4: new full speed USB device using ohci_hcd and address 107". With so many hubs all the suspend/resume cycles cause numerous delayed reactions... if 4-2.4.4.4 is an USB hub (4 hubs in series connected to the host), should I be able to connect a device to it or have I reached the limit already? When I do connect a device, the final hub in the chain disappears. 00:13.3 USB Controller: ATI Technologies Inc SB600 USB (OHCI3) (prog-if 10 [OHCI]) <1002:438a> Subsystem: Giga-byte Technology Device
