Linux Kernel USB Converter

Hello,

i have a problem with USB converter and i will be  grateful if you can
help me with this issue.

We have a USB-Serial converter. 8 coms. each comX connected to one
specific sensor. Normally, when we connect the USB-Serial to the PC,
linux create /dev/ttyUSB0-7 perfectly.but , sometimes, without
disconnect USB-Converter, kernel delete /dev/ttyUSB0-7 and create the
next group /dec/ttyUSB8-15. Is there any way to refresh USB port? This
also happen when the sw which open ttyUSBX port is running and the USB
converter is disconnected and reconnected, kernel create new ttyUSBX.


Thank you very much
