The rt73usb was reinitialized by uhci as full speed device then, but it did not work with wpa_supplicant, manual device removal was necessary, so it should be of no use if we add dvb-usb driver reinits on i2c failures, too. The disconnects with dvb-usb need reboot cause driver cannot be removed with modprobe. This long standing bug is really nasty and makes permanent high speed usb connections unusable on Linux, at least with this VIA hardware. No debug parms in modules, we need to ask linux-usb how to debug this. y tom ^ permalink raw reply [flat|nested] 6+ messages in thread

It always should be possible to remove the driver. > This long standing bug is really nasty and makes permanent high speed usb connections unusable on Linux, > at least with this VIA hardware. > > No debug parms in modules, we need to ask linux-usb how to debug this.

All 3 usb devices and 2 different series VIA usb hosts and Hemsing's and many other broken i2c comms reporter's on linux-media are broken instead? Well, if we get that confirmed, I'll buy 2 of those with NEC chipset: http://cgi.ebay.de/ws/eBayISAPI.dll?ViewItem&item=190318779935 > >> I was able to catch a dmesg err message like "ehci...force halt... handshake failed" once only. > > Can you please post the error message?

You may need to copy the "broken periodic workaround" code from the PCI_VENDOR_ID_INTEL case in ehci_pci_setup(), drivers/usb/host/ehci-pci.c into the PCI_VENDOR_ID_VIA case.
