Summary: STM32 USB driver unplugging/replugging issue
Product: eCos
Version: CVS
Platform: stm32e_eval (ST STM3210E EVAL board)
OS/Version: Cortex-M
Status: NEW
Severity: normal
Priority: normal
Component: USB driver
AssignedTo: unassigned@bugs.ecos.sourceware.org
ReportedBy: john@dallaway.org.uk

Class: Advice Request
There appears to be a problem with configuration of the STM32 USB driver
following unplugging and reconnection of the USB cable. This is observed with
both the USB mass storage and USB serial tests against a Linux host (CentOS 5).
For example, with the USB mass storage test (usbs_test_ramdisk):
a) run the test
b) mount the disk on a remote machine
c) check reading/writing of files on the FAT12 partition OK
d) unmount
e) unplug USB cable
f) reconnect USB cable
g) observe STM32 USB driver does not reach the configured state
Note that both the USB serial tests and the USB mass storage handler
usbs_msd_handler() are designed to loop and wait for a new connection by
calling usbs_*_wait_until_configured() following disconnection.
Has anyone else observed this issue?
