Hello Steven,
I have a ploblem in using usb 1.1 host , in my board(has not CPLD) I wanna using USB1.1 Host , and not using USB2.2 But usb1.1 Host is not working , when usb device is connected Kernel prints -62 err messages How can I Slove it?
Sorry for the late reply.
Looking at the logging, it seems that you are using the common OHCI driver. The logging I see appears familiar to me. It happens sometimes on some controllers (I do not expect it is USB stick related). It looks a bit like a startup issue, on our CPUs it occurs very infrequently and the problem is usually gone after a single reset. I still want to figure why it is happening sometimes.
Another option, which is more likely here, because the Linux kernel also has the same problem, is that the board specific initialisation is not entirely correct. Similar errors are also seen when the 48 MHz is not available (or configured wrong, at wrong frequency) for the OHCI controller. Usually U-boot needs to set up board timing, PLLs, etc. correct, the Linux kernel can depend on the bootloader configuration, but that might be different per architecture.
Kind Regards,
Remy
