Hi,
i am moving from kernel 3.5.1 to 3.17, on a custom AM1808(arm) based
board.I could have host usb working inserting a usb key, but after
removing it, a second insertion of the stick is not detected anymore.
I had to enable the broken Kconfig option into /drivers/usb/musb/Kconfig:
config USB_MUSB_DAVINCI
config USB_MUSB_DA8XX
tristate "DA8xx/OMAP-L1x"
depends on ARCH_DAVINCI_DA8XX
- depends on BROKEN
Even if the driver can work in OTG mode, i set up the MUSB controller
driver to work in MUSB_HOST mode, as it was in kernel 3.5.1, enabling the
same .config and board options.
Seems like something get corrupted after the first usb stick removal.
dmesg, booting
...
davinci_mmc da830-mmc.1: Can't get dma_tx channel
davinci_mmc da830-mmc.1: Using PIO, 4-bit mode

davinci-mcbsp davinci-mcbsp.0: Runtime PM disabled, clock forced on.
davinci-mcbsp davinci-mcbsp.0: Runtime PM disabled, clock forced on.
....
then, i insert the usb stick:

....
The i remove the usb stick
usb 1-1: USB disconnect, device number 2
FAT-fs (sda1): unable to read boot sector to mark fs as dirty
re-insert
nothing happen anymore.
I am studying into drivers to find a solutions.
Every help is veru appreciated.
Thanks
Regards
Angelo
