USB to Serial Port Converter   
Hi everybody,

I am using a convertor by Silicon Labs company for converting RS485 to USB. After some researching, i learned i must run
 devc-serusb in order to create a IO file for my converter, such as /dev/serusb1. My QNX didn't contains devc-serusb 
executable driver file, but i transffered it from Windows to QNX via SSH, put into /sbin directory, applied chmod 
command to run it. Now, i can run devc-serusb but it doesn't create a IO file in dev directory, no /dev/serusbX file. 

The converter is listed by usb (-vvv) command, i see its vid, did, bus, devno etc. When i use commands in http://www.qnx
.com/support/knowledgebase.html?id=50130000000mttO, devc-serusb doesn't run at this time. Obviously, i failed :(

Can you help me about how i can?
Best regards,

Orcun.

Re: USB to Serial Port Converter   
hi again,

i solved the problem, it arised from devc-serusb file in qnx sdk directory in my windows, i changed my devc-serusb with 
devc-serusb file of another qnx os. these files sizes are not same but they are files of same version (QNX 6.5). one of 
them was installed from qnx 6.5 cd, other one was installed from downloaded exe file from qnx web site. i think this may
 be more serious problem. despite it was solved i wonder, i will be happy if anybody can explain the problem.

best regards,

orcun.

Re: USB to Serial Port Converter   
can you attach both files: the one that didn't work and the one that did 
work?

There have been changes to devc-serusb between 6.5.0 and 6.5.0SP1:

From: http://www.qnx.com/developers/articles/rel_5189_3.html
"
What's new: Character drivers (devc-*)

devc-serusb
     This driver now supports these devices:

         Cinterion AHx module (Ref# 124687, 142316)
         Sierra Wireless AR8550 3G dongle (Ref# 117569, 142488)

     as well as the following features:

         CDC ACM; the driver automatically detects ACM devices, based on 
the USB Class code (Ref# 68333, 80267, 142175)
         a DCMD_CHR_RESET devctl() command that resets the device (but 
not all drivers use this command) (Ref# 80267, 142175)
         a drt option that lets you specify the data-ready timeout (Ref# 
116850, 142306)
