Same here... my device is a Microtrack II recorder with CF card storage:

lsusb output (before the errors):

** modprobe -r ehci_hcd doesn't work

** echo N > /sys/module/usbcore/parameters/old_scheme_first doesn't work

** changing cables or ports (front/back) doesn't work

I've heard that recompiling the kernel can help, changing the setting:

#define EHCI_TUNE_CERR          3       /* 0-3 qtd retries; 0 == don't
stop */

to

#define EHCI_TUNE_CERR          0       /* 0-3 qtd retries; 0 == don't
stop */

in drivers/usb/host/ehci-hcd.c, but this is beyond me.  Also people
saying that tweaking the kernel in other ways works, can't verify.
Anybody out there who can help?
