you're connecting a FS/LS device to EHCI port, that doesn't work. OMAP
can't handle port handoff to companion OHCI controller, then it fails
not being able to enumerate the device. Try remuxing your port to OHCI
controller and disabling EHCI from Kconfig.
It actually is a HS device (it's a 4-port hub) - when booting the
vendor supplied kernel (based off 2.6.32, i.e. pre -IR redesign), the
device identifies as follows:
Bus 001 Device 002: ID 05e3:0608 Genesys Logic, Inc. USB-2.0 4-Port HUB
with the following boot messages:
usb 1-2: new high speed USB device using ehci-omap and address 2
usb 1-2: New USB device found, idVendor=05e3, idProduct=0608
usb 1-2: New USB device strings: Mfr=0, Product=1, SerialNumber=0
usb 1-2: Product: USB2.0 Hub
hub 1-2:1.0: USB hub found
hub 1-2:1.0: 4 ports detected
I've pasted the boot log for my kernel:
http://pastie.org/1379102
And the boot log for the original kernel:
http://pastie.org/1379100
It could be a bug on the reset sequence on ehci-omap.c, do you have
anything connected to any of the hub ports ?
Please enable CONFIG_USB_DEBUG on your kernel config and grab a bit more
information.
Also, boot the machine without the device attached and after booting
run:
# dmesg -c
then attach the device, then grab the output of dmesg.
