It does happen on two different hosts here running different GNU/Linux
systems (Trisquel and Debian) and different kernel versions (3.2 and
3.13). The one that recovers properly is Debian/3.13.

It is definitely something else. I can see what appears to be the
BootROM when pressing AUX:

May  3 18:36:23 collins kernel: [ 6855.087475] usb 3-1: new high-speed USB device number 52 using xhci_hcd
May  3 18:36:23 collins kernel: [ 6855.104242] usb 3-1: unable to get BOS descriptor
May  3 18:36:23 collins kernel: [ 6855.105286] usb 3-1: New USB device found, idVendor=0451, idProduct=d00e
May  3 18:36:23 collins kernel: [ 6855.105291] usb 3-1: New USB device strings: Mfr=33, Product=37, SerialNumber=0
May  3 18:36:23 collins kernel: [ 6855.105294] usb 3-1: Product: OMAP3630
May  3 18:36:23 collins kernel: [ 6855.105297] usb 3-1: Manufacturer: Texas Instruments
May  3 18:36:26 collins kernel: [ 6858.108625] usb 3-1: USB disconnect, device number 52

Which disconnects properly indeed, but as soon as U-Boot starts, this
happens:

May  3 18:36:30 collins kernel: [ 6862.229542] usb 3-1: new full-speed USB device number 53 using xhci_hcd
May  3 18:36:35 collins kernel: [ 6867.233744] xhci_hcd 0000:00:14.0: Timeout while waiting for address device command
May  3 18:36:37 collins kernel: [ 6868.899141] usb 3-1: Device not responding to set address.
May  3 18:36:37 collins kernel: [ 6869.103329] usb 3-1: device not accepting address 53, error -71

Note that the U-Boot version I am using is the one from:
http://download.goldelico.com/gta04-main/20140103-GTA04-3.12.0-wheezy-7.3/

Maybe someone else is experiencing the same issue with a GNU/Linux
distribution on the host?
