Just speculating, git log -SNEW_SCHEME yields 48fc7dbd52c0559647291f33a10ccdc6cdbe4c72, it looks similar to the other interesting patches. >> Thanks very much for the patch; I tested your branch with my Carelink >> stick and it works sometimes. >> >> Here's an example of it working as expected: > That's good.

For some reason, it started enumerating consistently for awhile, failed once, and then enumerated consistently until I gave up. I cherry-picked your e2c7df19e2734f5d54d0d942a57d1018539e02c4 on 3.14-rc7, which applied cleanly. Your changes work as expected here. The carelink usb stick did enumerate once or twice, here is a log: https://gist.github.com/bewest/6488955#file-example-3-14-0-rc7-working-log I still often get failure to enumerate after inserting the usb stick: I didn't keep an exact count, but this feels like a more consistent failure somehow.

At some point, I got the following messages in the logs. After receiving these messages, I tried several different usb devices, but they all fail to enumerate after this. Sarah's branch seemed to enumerate consistently, but hard to quantify; I'll bang on it a bit more, and try to keep track of error vs success rates. -bewest P. S. I wasn't doing my usual log capture routine, but I believe I saw these messages, after which no log messages appear, even when inserting/removing other usb devices. https://gist.github.com/bewest/6488955#file-broken-usb-stack-log Linux patient 3.14.0-rc7-bewest-test-3.14-rc7-carelink-01 #6 SMP Wed Mar 19 21:12:24 PDT 2014 x86_64 x86_64 x86_64 GNU/Linux Mar 20 08:03:16 patient whoopsie[1220]: online Mar 20 08:04:37 whoopsie[1220]: last message repeated 2 times Mar 20 08:05:37 whoopsie[1220]: last message repeated 3 times Mar 20 08:05:40 patient kernel: [28385.152074] xhci_hcd 0000:00:14.0: Timeout while waiting for a slot Mar 20 08:05:40 patient kernel: [28385.152081] hub 3-0:1.0: couldn't allocate port 2 usb_device Mar 20 08:06:24 patient NetworkManager[867]: <warn> nl_recvmsgs() error: (-33) Dump inconsistency detected, interrupted Mar 20 08:06:37 patient whoopsie[1220]: online Mar 20 08:07:37 whoopsie[1220]: last message repeated 2 times Mar 20 08:08:37 whoopsie[1220]: last message repeated 3 times Mar 20 08:09:56 patient whoopsie[1220]: online Mar 20 08:11:08 whoopsie[1220]: last message repeated 2 times Mar 20 08:12:08 whoopsie[1220]: last message repeated 3 times Mar 20 08:13:16 patient whoopsie[1220]: online Mar 20 08:13:17 patient whoopsie[1220]: online Mar 20 08:13:21 patient bluetoothd[781]: Adapter /org/bluez/781/hci0 has been disabled Mar 20 08:13:21 patient bluetoothd[781]: Unregister path: /org/bluez/781/hci0 Mar 20 08:13:21 patient bluetoothd[781]: Endpoint unregistered: sender=:1.52 path=/MediaEndpoint/A2DPSink Mar 20 08:13:21 patient bluetoothd[781]: Endpoint unregistered: sender=:1.52 path=/MediaEndpoint/A2DPSource Mar 20 08:13:21 patient bluetoothd[781]: Endpoint unregistered: sender=:1.52 path=/MediaEndpoint/HFPAG Mar 20 08:13:21 patient bluetoothd[781]: Endpoint unregistered: sender=:1.52 path=/MediaEndpoint/HFPHS Mar 20 08:13:21 patient colord: device removed: sysfs-Generic-BisonCam__NB_Pro Mar 20 08:13:21 patient kernel: [28846.341209] xhci_hcd 0000:00:14.0: xHCI host not responding to stop endpoint command.
