Hi there, I've been working a bit on USB / HID (hiddev) for supporting MGE UPSs units, which was working fine in earlier kernels (latest was 2.5.13 with a patch). As Vojtech Pavlik and Paul Stewart have now integrated hiddev in 2.5 kernel and have added a new ioctl in hiddev, I wanted to test it but failed with 2.5.33 release. It seems that the communication is broken between uhci and hidcore. Following the hotplug, hiddev driver seems "freezed". What more can I do to help solving this issue ? Thanks. Arnaud Quette R&D Service - MGE UPS SYSTEMS ps : I'm waiting for this feature to work for releasing HiddevBrowser (a kind of usbview for hiddev devices)... Here are all (I hope) information needed : Context : Suse 8.0, kernel 2.5.33, uhci controler, various MGE UPS units syslog ******* ...
