Thank you Alan.

I have modified the uhci driver to accept the buggy configuration. And now the printer works...

Hi Bruno, Can you post that patch, at least for posterity?

Thanks.

Hi,

Anybody knows why it should not be possible
to have an endpoint in bulk mode for a low speed device ? The uhci_submit_bulk function in uhci-hcd.c returns -EINVAL in that case.


But according to /proc/bus/usb/devices, the device I'm trying to use (DYMO LabelWriter 320) is a low speed one with bulk endpoints.

It's not possible because the USB specification says that low-speed devices are only allowed to support control and interrupt endpoints.
Apparently your device contains an illegal configuration.
