Help with testusb

Hello all,

I'm trying to run testusb on a tusb6010 device to test it's host mode
functionalities. I compiled the latest linux-omap gittree and enabled
the OTG mode.

I'm setting it to host mode by echoing "host" to
/sys/devices/platform/musb_hdrc/mode.

Here's my scenario:
1. 1 TUSB6010 set to host mode;
2. 2 Mini-b <-> A cable
3. 1 female <-> female USB-A cable;
4. 1 OMAP H2 running as gadget zero; (the testing device)
5. 1 selfpowered USB 2.0 HUB;
6. 1 Mass storage device to copy the testusb binary to device's /tmp;


My procedure:
1. Turn on TUSB6010;
2. Set it to host mode;
3. plug the mini-b <-> A cable to the USB HUB
4. plug the mass storage device to the hub
5. copy testusb binary to device's /tmp
6. mount usbfs on /proc/bus/usb
7. run ./testusb -a


Results:
I ran two tests, either gave me different error messages...

When I ran the same tests with my PC I've got better error messages:
take a look:

What could I do to make this tests work ??
Thank you all...
