Subject[PATCHv2] phy: cpcap-usb: Fix flakey host idling and enumerating of devices
Date
We must let the USB host idle things properly before we switch to debug
UART mode. Otherwise the USB host may never idle after disconnecting
devices, and that causes the next enumeration to be flakey.

Kishon, looks like the v1 patch sent in August got lost somewhere.
Here's a resend update against your fixes branch.
