This seems to be a problem you have with Microsoft Windows 7, is that correct? Or do you rather get the error message 'This device cannot start (code 10)' on Linux? If so, please post a more complete error log. Also, the output of "lsusb -v" might help. HTH, Jonathan Neuschäfer

Fwd: Mounting issue
by tomy June 10, 2013

June 10, 2013

Hello, Currently I am working on an embedded system which is having 512 MB NAND flash . The embedded system is having u-boot, kernel, root filesystem (JFFS2) and a backup file system all reside in NAND flash. I am now facing a booting issue randomly (/*reboot */command from linux console ) and the snapshot of the error is given below / //udevd-work[1092]: '/etc/udev/scripts/network.sh' unexpected exit with status 0x000b// //udevd-work[1089]: '/etc/udev/scripts/network.sh' unexpected exit with status 0x000b// //udevd-work[1032]: '/etc/udev/scripts/mount.sh' unexpected exit with status 0x000b// // // //udevd-work[1112]: '/etc/udev/scripts/network.sh' unexpected exit with status 0x000b// // // ///etc/init.d/rc: line 45: 1760 Segmentation fault "$@"// ///etc/rcS.d/S37populate-volatile.sh: line 194: 1773 Segmentation fault sh /etc/volatile.cache// //ln: /var/run/ld.so.cache: No such file or directory// ///etc/init.d/rc: line 45: 1780 Segmentation fault "$@"// ///etc/rcS.d/S55bootmisc.sh: line 68: 1784 Segmentation fault /etc/init.d/hwclock.sh start// // //INIT: Entering runlevel: 5/ After this, the board is not pinging and not able to login through console and the only solution to recover from this is power reboot. But in the next reboot everything will be ok. The problem is happening randomly may be in 30 or 40 software reboots. I am not sure whether the issue is happening because of mounting problem, but still why this is not happening in every reboots. So can you people help me to find out the root cause of this problem.

bonding balance-alb tons of null info packets.

Here is my bonding configuration - modprobe bonding mode=balance-alb miimon=100 ifconfig bond0 192.168.30.3 netmask 255.255.255.0 up ifenslave bond0 p255p1 ifenslave bond0 p255p2 cat /proc/net/bonding/bond0 bond0 has two interfaces p255p1 (bb:36) and p255p2 (bb:37) I see tons of same src-mac (slave), dst-mac (same slave) packets, length of 0x60 with NULL payload on each interfaces - coming up to the switch.

Just to be sure... I just downloaded a clean copy of kernel 3.6.9. I then configured it for UAC1 and the USB Audio Gadget. I rebuilt and installed the g_audio loadable module. Again I get the 'This device cannot start (code 10)' Error when I connect windows 7. My expectation is that that this should work with the default windows drivers - Is this correct.

I'm trying to use the linux usb audio gadget but I get the error : "This device cannot start (code 10) when I connect to a windows 7/8 box. I don't have this problem when I connect to ubunto 12.0.4 I'm current using kernel 3.6.9, but have also had the issue with an older kernel (2.6.39.4). I'm not sure if this is an appropriate issue for this mail list, but I need to get a resolution to this... Thanks for your help. Eamon.
