CDC Driver issue of CC2531(RF Modem Application)
I am facing a problem with driver installation for 2 dongle on same
When I connected single dongle it install the driver and detect as a
com-port. But when I connect the another dongle it disables the first one and
also do not detect the new one. I am not facing this problem with windows7. Both dongles are working on the same pc and at a same time when OS is Windows 7 but whenever I switch to Windows XP I can detect only dongle at a time .
Anybody please let me know details on it.
you should associate different serial number to the CC2531 device you're enumerating, so you can have multiple simultaneous instances of the same VID and PID.
The serial number is hard-coded as an example in the driver to a specific value. Are you using the RemoTI stack?
If you are, please verify the usb_RemoTICdcDescriptor.s51 and look up the string3Desc structure (serial number string definition).
When operating with Windows XP driver manager system and using simultaneous devices with same vendor ID and Product ID, the devices should have different serial numbers. Please change it and upgrade the firmware according to your use cases.
I am not using Remo TI stack. I am just using the USB example of CC2531. I am using simple RF USB modem program for my application. As requirement is convert USB data to wireless.
How two associate two different serial numbers to CC2531 device in that case.
I am sorry but this forum is related to RemoTI Stack and SW. Anyway, even though you're not using the RemoTI stack, the device driver architecture in your SW base should be the same and you should be able to locate easily, through IAR workspace, the pre-defined USB descriptor configuration in HAL/Target/CC253xUSB/USB/class_cdc (or something very similar). Then try to locate the usb_xxxxxcdcDescriptor.s51 where the SerialNumber is hard-coded.
Just using different SerialNumber IDs for the whole devices you want to enumerate will allow you to support multiple enumeration on Windows XP OS.
How do you intend to use the CC2531 device then? Is it for a Zigbee application?
Thanks for your help again.
I will work on this and will late you know
Yes you are right this wrong forum for my question but My post was automatically moved to this forum initially i posted it under LPRF. I will use CC2531 for USB to wireless communication. It is just point to point communication hence no Zigbee stack involoved.
