[U-Boot] USB only works in Linux if started in UBoot
hi
I was wondering what I was doing wrong here !
The USB functionality in Linux only works if I run 'usb start' in UBoot before starting the kernel.
Not sure what will resolve this, of course I can make automatic start command during starting of the bootloader but I think that's not optimal.
Any thoughts on this ?

What hardware are you running on? What kernel version are you using? What U-Boot version are you using?
This issue was present on some Freescale CPUs, but has been fixed in the mainline kernel by the following commit in case you're running on one of their CPUs: http://git.kernel.org/?p=linux/kernel/git/next/linux-next.git;a=commitdiff;h...
Best, Peter
hi
of course I forgot to mention my platform, sorry about that
CPU: MPC5200b Kernel: 2.6.33-rc6 Uboot: U-Boot 2009.03
