| |
Hi, i am having the problem that sometimes after suspend/resume on a Sony Vaio C1MHP the ohci usb driver does not discover new devices anymore. I unload the module before suspend so i did not expect any problems.

Multiple remove/insert loops dont solve the problem. Something seems to stay uninitialized ..
