Hello Martins,
It seems like a speed problem:
[  186.450841] ehci_hcd 0000:00:1d.7: GetStatus port:2 status 001403 0
 ACK POWER sig=k CSC CONNECT
[  186.450854] hub 1-0:1.0: port 2, status 0501, change 0001, 480 Mb/s
...
[  186.605119] hub 2-0:1.0: port 2, status 0301, change 0001, 1.5 Mb/s
[  186.709035] hub 2-0:1.0: debounce: port 2: total 100ms stable 100ms
status 0x301
[  186.811038] usb 2-2: new low speed USB device number 5 using uhci_hcd

Apparently the kernel can't decide between using UHCI (for USB 1.0) or
EHCI (for USB 2.0).
Is the OHCI HCD support activated in the kernel? (Which supports USB 1.1)
My guess will be to try with that.

Greetings,
Juan Alberto.
