Hi all,

We have USB ECHI port 1 integrated with SMSC PHY (USB 3326) on Beagle Board. I have connected a high speed Mass Storage (USB harddisk) to the port, the enumeration happens fine and I am also able to do a data transfer, but after some time, it fails with below message:

I have also tried connecting a self powered HUB, this fails as well. Other USB devices like Ethernet, Mouse, Keyboard, etc fail after similarly.

We have done USB eye diagram tests and found no issues with hardware as such.

Any pointers on these should be helpful, let me know if you need any further info.

FYI, I am using drivers/usb/host/ehci-omap.c on latest OMAP GIT.

Hardware reference manual for Beagle can be found here,

it could be that you're using a full speed storage device.

From Beagle Manual:

"NOTE: Beagle USB Host only supports HS USB (480Mbp/S). Low Speed
and Full Speed devices are not supported unless they are connected
through a USB Hub prior to connection to the Beagle. The OTG port
does support LS and FS devices."

also try applying this patch to wait a bit more for reset bit to be
cleared:

I'm having similar issues with usbon the beagleboard:

usb 1-1: USB disconnect, address 2
usb 1-1.3: USB disconnect, address 7
eth0: unregister 'asix' usb-ehci-omap.0-1.3, ASIX AX8817x USB 2.0
Ethernet
usb 1-1: clear tt 4 (9082) error -19
usb 1-1: clear tt 4 (9082) error -19

I tried various combinations of the usb-ethernet adaptor with and
without hub and found:

* no hub, low cpu load + slow transfer (e.g. download over adsl):
transferring a few MiBs is OK
* hub, low cpu load + slow transfer: transferring ~ 1MiB is OK
* big cpu load (e.g. using scp): 128KiB max

I didn't dare to try a USB disk yet :)

Koen

I've uploaded a kernel with your timeout patch and a modular ehci_hcd
(so you need to unpack modules.tgz into your rootfs) to here:

http://amethyst.openembedded.net/~koen/beagleboard/usbtest/

I'm currently 700 km from my beagleboard, so testing is appreciated :)

regards,

Koen

I'm having a different problem, I'm running a 500 Mhz beagle and
trying to connect to a USRP (www.ettus.com). I've seen the firmware
load once or twice, but mostly I get this :

Was usbdevfs mounted with:

mount -t usbdevfs none /proc/bus/usb

?

Yes, usbfs is mounted.

I collected the errors after trying to load the USRP firmware with the
.22 kernel installed.
