Hi all, My OMAP37 board started choking on my USB mouse when I updated from 2.6.37 to 2.6.38rc5. I've tracked it down to commit d199c96d41d80a567493e12b8e96ea056a1350c1, "USB: prevent buggy hubs from crashing the USB stack." If I revert this commit, my mouse works again. Otherwise, I get the message: usb 1-1: new low speed USB device using musb-hdrc and address 33 usb 1-1: parent hub has no TT repeatedly (with 'address' incrementing). I'm using the musb-hdrc driver for the OTG USB port in host mode. some relevant config: CONFIG_USB_EHCI_HCD_OMAP=y CONFIG_USB_MUSB_HDRC=y CONFIG_USB_MUSB_OMAP2PLUS=y CONFIG_USB_MUSB_HOST=y CONFIG_USB_MUSB_HDRC_HCD=y CONFIG_USB_INVENTRA_DMA=y # lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Any thoughts on how to get around this besides just reverting the commit? Did anybody already encounter this? thanks, Michael MATRIX VISION GmbH, Talstrasse 16, DE-71570 Oppenweiler Registergericht: Amtsgericht Stuttgart, HRB 271090 Geschaeftsfuehrer: Gerhard Thullner, Werner Armingeon, Uwe Furtner -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
