MUSB HDRC DRIVER DOWNLOAD
You can find it: If you do not see the debug filesystem, then you can add it by doing the following in the kernel config. Here is what I do on our device after boot:. By unbinding the musb hub controller, i can see that all usb devices connected to this hub are really turned off. The other problem occurred today. Here is the init code of the USB driver:.

Thank you very much!

Site Search Log in. I am currently running armhf and so unable to test it.
I’m sure you dont’t want to unbind the musb controller driver, instead it’s unbinding the device. Thanks for your help. When writing an musb glue layer for a more complex controller hardware, you might need to take care of more processing in those two functions. Note that Steven’s method only applies to hrdc the controller in host mode.

How that happened that this register has different values every time I start it and what is the meaning of those bits? This page has been accessed 9, times.
First of all, keep in mind that there is a difference between a logical Device and a Device Driver. Sometimes it has “0x” value this is the case when USB is not working at allsometimes “0x” the case where is USB fully working.
Linux File-Backed Storage Here is also log from my laptop: Acting as the counterpart of init, the exit function releases the MUSB PHY driver when hdec controller hardware itself is about to be released. I will also look for an alternative. Some variants might only support 4 fully flexible endpoints in slave mode at the same time.
Or you can just follow the driver link: Unfortunately, there is no difference in kernel logs when USB works and when it does not. Hello again, this time I disabled Musbb drivers and tried to set up registers manually. It says it’s using ehci-pci driver, but the device will be binded to a hub instead.

Note that we are not using device tree bindings here. On my board AM33x Sitarathere are 2 usb controllers with musb-hdrc drivers bind to them: SETUP packet len 0! At that point of the registration process, the controller driver actually calls the init function:.
Have you tried the other two solutions I suggested? Hello, I am still working on this USB issue. USB Mass Storage device detected [
