Hello Martins,
It seems like a speed problem:

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.
Hi Juan,
Thanks for the reply! I started with the config used for the ubuntu
system running on my system and ran make oldconfig. Currently under USB
support I have the following included:
Support for Host-side USB
USB verbose debug messages
USB announce new devices
*** Miscellaneous USB options ***
USB device filesystem (DEPRECATED)
USB Monitor
*** USB Host Controller Drivers ***
xHCI HCD (USB 3.0) support (EXPERIMENTAL)
EHCI HCD (USB 2.0) support
Root Hub Transaction Translators
Improved Transaction Translator scheduling
OXU210HP HCD support
ISP 1760 HCD support
OHCI HCD support
UHCI HCD (most Intel and VIA) support
*** USB Device Class drivers ***
USB Printer support
USB Mass Storage support
The shared table of common (or usual) storage devices
Should I possibly not include some of this?
Martins
