I am trying to use usbip with my Brother HL-2030 USB printer.
The server is an x86 machine (a laptop, debian squeeze) and the client an amd64 machine (another laptop, running ubuntu 11.04). Both run stable 2.6.39.2 kernel compiled with usbip and its debug option.
I can print out the first job, one or several pages. Something goes wrong during the second job on the server. The second and later jobs do not print. Dmesg of the server contains the attached text.
Does anyone have an idea how to solve it or where to turn for help?
Dear All,
I am trying to use usbip with my Brother HL-2030 USB printer.
The server is an x86 machine (a laptop, debian squeeze) and the client an amd64 machine (another laptop, running ubuntu 11.04). Both run stable 2.6.39.2 kernel compiled with usbip and its debug option.
I can print out the first job, one or several pages. Something goes wrong during the second job on the server. The second and later jobs do not print. Dmesg of the server contains the attached text.
Does anyone have an idea how to solve it or where to turn for help?
Kind Regards, sparlampe
