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

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

Anybody got any ideas? :-)
Bye
