We can use a usb_mid and/or scsa2usb binding instead of a blacklist, but generally the cases where you'd need usb_modeswitch are where the device only present one endpoint. usb_modeswitch appears to be based on libusb so it may actually be portable. > maybe we can implement a way to > handle this kind of devices, I really like to check if this anyData ADU-520a > works with usbsacm(7D), I also understand that maybe this is more a issue > for Illumos guys, but I bet most of them also read this list. > That is not a good assumption as this is not a developer list, please use illumos-developer. -Albert _______________________________________________ OpenIndiana-discuss mailing list OpenIndiana-discuss@openindiana.org http://openindiana.org/mailman/listinfo/openindiana-discuss
