Hello all. I originally moved from 3.8.13 to 3.14.17 to grant cryptography capabilities of the new kernel, and everything seemed okay until I had an issue regarding USB Babble interrupts. I could test for babble cases reliably as described here <http://www.spinics.net/lists/linux-usb/msg107573.html>. With kernel 3.14.17, when the Babble occurs, the log enters an endless loop of:
[ 121.501538] CAUTION: musb: Babble Interrupt Occurred [ 121.506785] musb_stage0_irq 789: unhandled DISCONNECT transition (a_wait_bcon) and I could only escape this loop by detaching and attaching the device. However, I moved to 3.14.25 that seems to pass the Babble test, I could plug/unplug various devices and everything seemed okay. I connected a USB hub (powered) and I could reach it, but not the devices attached to it: Bus 001 Device 004: ID 0424:2514 Standard Microsystems Corp. USB 2.0 Hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub When I tried to reset the USB hub, I kept getting these two lines until I detach the USB cable: [ 181.632279] usb 1-1: reset high-speed USB device number 2 using musb-hdrc [ 181.751895] usb 1-1: device descriptor read/64, error -71 Please find a full log of the 3.14.25 attached. Thank you for your time and help.
