Title: USB CDC/ACM HOST CLASS DRIVER
Desciption: A CDC/ACM host class driver has been added. This has been
testing by running the USB CDC/ACM host on an Olimex
LPC1766STK and using the configs/stm3210e-eval/usbserial
configuration (using the CDC/ACM device side driver). There
are several unresolved issues that prevent the host driver
from being usable:
- The driver works fine when configured for BULK-ONLY
operation.
- Testing has not been performed with the interrupt IN channel
enabled (ie., I have not enabled FLOW control nor do I have
a test case that used the interrupt IN channel). I can see
that the polling for interrupt IN data is occurring
initially.
- I test for incoming data by doing 'nsh> cat /dev/ttyACM0' on
the Olimex LPC1766STK host. The bulk data reception still
works okay whether or not the interupt IN channel is enabled.
If the interrupt IN channel is enabled, then polling of that
channel appears to stop when the bulk in channel becomes
active.
- The RX reception logic uses the low priority work queue.
However, that logic never returns and so blocks other use of
the work queue thread. This is probably okay but means that
the RX reception logic probably should be moved to its own
dedicated thread.
- When the cable connecting the STM3110E-EVAL device is
removed, the software on the Olimex LPC1766STK crashes. The
crash is due to corruption of the OHCI bDoneHead pointer.
Most of these problems are unique to the Olimex LPC1766STK DCD; some are probably design problems in the CDC/ACM host driver. The bottom line is that the host CDC/ACM driver is immature and you should probably not use it unless you want to invest some effort.
Status: Open
Priority: Medium-Low unless you really need host CDC/ACM support.
