I'm testing these patches with an AM33xx board that has the first musb port wired to an USB type A plug, but it doesn't yet work for me. The messages I'm getting are: [ 1.219339] ehci_hcd: USB 2.0 'Enhanced' Host Controller (EHCI) Driver [ 1.226568] ohci_hcd: USB 1.1 'Open' Host Controller (OHCI) Driver [ 1.233444] usbcore: registered new interface driver uas [ 1.239066] Initializing USB Mass Storage driver...

I'm unsure on how to fix this, and I didn't get an answer yet to that question when I asked Felipe about how interface drivers like dsps are supposed to act in order to get host mode back after the recent musb cleanups. What type of hardware do you test this with? Does host mode work for you?
