Hello.
This NEC USB-Controler cannot use USB2 Devices.
USB1 Devices work.
I have done tests in Windows XP, with USB-drivers installed.
It tells: "Highspeed USB devices with non highspeed interface"
I made efforts with Linux kernel 2.6.3, and the same problem:
With the difference...the kernel is talking, windows don't
The USB-Scanner doesn't apear at all in lsusb.
The NEC-Controler on the MSI-Board:
00:0b.0 USB Controller: NEC Corporation USB (rev 41)
00:0b.1 USB Controller: NEC Corporation USB (rev 41)
00:0b.2 USB Controller: NEC Corporation USB 2.0 (rev 02)
usb 7-3: new high speed USB device using address 2
usb 7-3: device not accepting address 2, error -71

usb 7-2: new high speed USB device using address 5
usb 7-2: device not accepting address 5, error -71
usb 4-2: new full speed USB device using address 2
I tested with the USB2 Scanner Epson 2450 Perfection Photo.
Now I had to install an usb pci card:
The new Controler:
00:0a.0 USB Controller: ALi Corporation USB 1.1 Controller (rev 03)
00:0a.1 USB Controller: ALi Corporation USB 1.1 Controller (rev 03)
00:0a.2 USB Controller: ALi Corporation USB 1.1 Controller (rev 03)
00:0a.3 USB Controller: ALi Corporation USB 2.0 Controller (rev 01)
The scanner also has some problems with this Controler, but the device is
now listed in lsusb and it works most times.
Sometimes I have to reconnect the Scanner because of
kernel: usbfs: USBDEVFS_BULK failed dev 2 ep 0x81 len 6 ret -75
kernel: usbfs: USBDEVFS_BULK failed dev 2 ep 0x81 len 4 ret -75
I would prefer to use the internal USB2, because of IRQ-problems (other
Thread) and too many PCI-Cards.
Is there a possibility to disable the NEC-Controler? Only the VIAs can be
disabled in the bios.
sincerely,
Paolo
