Hello,
I am using an OMAPL138 and having some trouble with USB Host mode for hosting USB flash. I can only get the 2.0 port (USB0) to function at 12Mbps. The issue appears to be with the root hub:
hub 2-0:1.0: debounce: port 1: total 100ms stable 100ms status 0x100
hub 2-0:1.0: state 7 ports 1 chg 0000 evt 0002
ohci ohci.0: GetPortStatus(1)
hub 2-0:1.0: port 1, status 0101, change 0001, 12 Mb/s
ohci ohci.0: GetPortStatus(1)
ohci ohci.0: GetPortStatus(1)
ohci ohci.0: GetPortStatus(1)
ohci ohci.0: GetPortStatus(1)
ohci ohci.0: GetPortStatus(1)
hub 2-0:1.0: debounce: port 1: total 100ms stable 100ms status 0x101
ohci ohci.0: GetPortStatus(1)
usb 2-1: new full speed USB device using ohci and address 3
ohci ohci.0: GetPortStatus(1)
usb 2-1: not running at top speed; connect to a high speed hub
usb 2-1: default language 0x0409
usb 2-1: udev 3, busnum 2, minor = 130
usb 2-1: New USB device found, idVendor=13fe, idProduct=1f00
usb 2-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
usb 2-1: Product: DataTraveler 2.0
usb 2-1: Manufacturer: Kingston
usb 2-1: SerialNumber: 5B83170002B3
usb 2-1: usb_probe_device
usb 2-1: configuration #1 chosen from 1 choice
usb 2-1: adding 2-1:1.0 (config #1, interface 0)
The bolded lines above seems to indicate the problem. There is no external hub connected, the USB stick is connected directly to USB0 pins on the OMAP. Any USB flash device I have tried has the same issue. File transfer rates are extremely slow.
Any help greatly appreciated. Thanks!
