Hello Anthony, which qemu-kvm version do you expect to work with serial usb devices?
After you've changed this ticket status and I've checked it again with qemu-kvm version 0.12.4. The reported error message is gone away and the device is present in the guest. The cdc_acm driver loads too without any visible problems, but the device is still unusable. The device data led flash if it gets un/initialized by minicom. But if I try to make a test dial, nothing happens after I call a phone number. To be more precise: -host dosn't have loaded the cdc_acm driver -guest loads the cdc_acm driver -a dial with minicom to the same phone number works on the host, if I load the cdc_acm within the host I would like to get this fixed, as I really want to use this usb-device as my dusty fax again. -- serial usb-device can't be passed-through to a guest https://bugs.launchpad.net/bugs/319014 You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. Status in QEMU: Fix Released Status in CentOS: New Bug description: Hello, I use Debian Lenny with qemu/kvm version 79. If I try to pass-through my "US Robotics 56K USB Modem Model 5637" to any guest, I get an perror("usb_linux_update_endp_table"). So, I've searched through the qemu-devel archives and found the following thread: http://www.archivum.info/qemu-devel@nongnu.org/2008-10/msg00299.html If I remove the "return 1;" as stated above my usb modem get's successfully passed-through to the guest and the modem works fine. Is there any chance to get serial usb devices to work out of standard qemu/kvm, without the need to apply this line to every qemu/kvm version? NicoP.
