Now that this driver is in the kernel (I'm running 2.6.15), there are some problems I'd like to report when using it. Basically, Junxion found this problem as well and posted a patch [http://www.junxion.com/opensource/linux_highspeed_usbserial.html]. I know it solves the problem, but the solution may be worse than the disease. Here is the problem, when you are moving "large" amounts of data or have a very high packet rate then the driver starts wigging out. The device will send data to the terminal, but it cannot recieve data - or visa versa. The only way to recover from this is disconnect the device and reconnect it. The Junxion patch simply increases the size of the buffer for the driver. I don't know if the reason this is needed is a problem with the Qualcomm EVOD Modem device itself or there is a bug in the serial driver. My money is on the former ;) So, is my real question is: Is this patch the solution? Is there a betetr solution? I have tried to get the data sheet for the EVDO Qualcomm chip, but I can't seem to find it or get anyone to talk to me. What's the next step? ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc. Do you grep through log files for problems? Stop!
