Hi,
we are using an board with a OMAP L138 with a exar xr21v141x [1], an
usb to two serial port converter. The exar have drivers [2] for
linux but aren't on mainline.
We are having problems when using both ports at same time, the
driver only receive the information from one port after the other
was closed.
On musb_core.c there are some information about problems with
multipoint devices. The behaviour that we are seeing is due to this
?
Any way of resolve this, being able to receive data from both ports
when both are open ?
We are having problems compiling the latest release of linux-davinci
kernel with usb support, even usb 1.0 interface don't work. Any info
about this ?
As you are stuck using their out-of-tree driver, I suggest you ask them
about this, as there's nothing we can really do here to help you out :(
I will ask to them but one issue is that the driver works on i386.
The musb_core.c have some comments about possible problems and I am
thinking if this device can demonstrate one of it :-/
Is a way of validating this ?
Now we could take their driver and add it to the kernel tree, but that's
a more long-term solution, not something to help you out right now,
sorry.
If license allow it, anyone can pick on the driver and try to submit ?
Don't need someone from the company or someone that maintain the driver ?
Thanks for your time.
