Re: g_vfs_done() error=5 USB disk on raspberrypi. Decrease the speed of USB
Hello, The drive is healthy (SMART OK) I played with hw.usb.umass.throttle, with value 10 and 100. It slow down the USB transfert and decresase the %system load ~10%. But I kept the normal value (0), the system succeed to dd 10GB to the USB drive without crashing If it reoccur I'll rebuild a kernel with USB_DEBUG, and this thread will be updated. Thanks for your support Hans.

Re: g_vfs_done() error=5 USB disk on raspberrypi. Decrease the speed of USB
Hi, If you set: hw.usb.umass.throttle=xxx Then it might have the same effect! Needs "options USB_DEBUG" in the kernel configuration file. SYSCTL_INT(_hw_usb_umass, OID_AUTO, throttle, CTLFLAG_RWTUN, &umass_throttle, 0, "Forced delay between commands in milliseconds"); --HPS ___ freebsd-usb@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-usb To unsubscribe, send any mail to "freebsd-usb-unsubscr...@freebsd.org"

And I didn't succeed to fix it with camcontrol Can you guide me on my investigation to decrease the speed of USB ? Hi, If you connect your USB device through an external full speed USB HUB, it will go full speed. It is possible to make all RPI-B devices enumerate at full speed too, but then you will have decreased network performance. Is you external USB device known to be buggy? --HPS ___ freebsd-usb@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-usb To unsubscribe, send any mail to "freebsd-usb-unsubscr...@freebsd.org"
