"bulk write: Resource temporarily unavailable” - LCD4LINUX

Hi there,

i have a problem with my pearl dpf. I patched this display one year ago for my fritzbox. It runs perfect. No problems.

Now i wanted to try the same frame on my raspberry and the only message i was get is

"bulk write: Resource temporarily unavailable” Now I patched the dpf with the latest FW 0.3. and the problem is the same. I know the rapsberry had problems with usb powering. I tried already with similar usb cables, y-usb cabel, two powered usb hubs, directly on the rpi, other ac/dc powerd inputs and so on.

nothing will help.

I had also tryed to go directly with 5V on the frame -> no powering problem, but the problem still alive.

i don't know more what I can do. Can anyone help me?

Das hat geholfen:

wer probleme mit usb-hubs hat, sollte in der "/boot/cmdline.txt" folgendes austauschen:

Code:

dwc_otg.microframe_schedule=1 smsc95xx.turbo_mode=N sdhci-bcm2708.missing_status=0 sdhci-bcm2708.sync_after_dma=0 dwc_otg.lpm_enable=0 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 rootwait dwc_otg.speed=1

heisst: alten text komplett raus löschen und den obigen einfügen!
