Hiho! :-) I got myself a new ebook reader (Onyx M92), but encountered a strange problem when connecting it to my freebsd machine. Shortly after mounting it, the device gets disconnected (causing the mounted storage to disappear). There is no such behavior with Windows 7. uname -a: FreeBSD xxx 11.0-CURRENT FreeBSD 11.0-CURRENT #11 r258254M: Sun Nov 17 13:38:01 CET 2013 xxx:/usr/obj/usr/src/sys/SUBMARINE_SMP amd64 The device identifies as follows: Dec 2 17:45:51 ubm kernel: ugen4.2: <Linux 2.6.35.3-gd7932e6-dirty with fsl-usb2-udc> at usbus4 Dec 2 17:45:51 ubm kernel: umass0: <Mass Storage> on usbus4 Dec 2 17:45:51 ubm kernel: da0 at umass-sim0 bus 0 scbus3 target 0 lun 0 Dec 2 17:45:51 ubm kernel: da0: <Linux File-Stor Gadget 0326> Removable Direct Access SCSI-2 device Dec 2 17:45:51 ubm kernel: da0:40.000MB/s transfers Dec 2 17:45:51 ubm kernel: da0: 3156MB (6463552 512 byte sectors: 255H 63S/T 402C) Dec 2 17:45:51 ubm kernel: da0: quirks=0x2<NO_6_BYTE> I tried setting (widly guessing): hw.usb.power_timeout: 30 -> 0 hw.usb.no_cs_fail: 0 -> 1 but to no avail. Setting "hw.usb.debug: 1" yields no additional output. usbconfig dump_device_desc yields: ugen4.2: <File-backed Storage Gadget Linux 2.6.35.3-gd7932e6-dirty with fsl-usb2-udc> at usbus4, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON (2mA) bLength = 0x0012 bDescriptorType = 0x0001 bcdUSB = 0x0200 bDeviceClass = 0x0000 bDeviceSubClass = 0x0000 bDeviceProtocol = 0x0000 bMaxPacketSize0 = 0x0040 idVendor = 0x0525 idProduct = 0xa4a5 bcdDevice = 0x0326 iManufacturer = 0x0001 <Linux 2.6.35.3-gd7932e6-dirty with fsl-usb2-udc> iProduct = 0x0002 <File-backed Storage Gadget> iSerialNumber = 0x0003 <3230204E6F76> bNumConfigurations = 0x0001 Anybody got any ideas? :-) Bye Marc
