You may need to use a powered hub
Many laptops do not put out enough of a level to work properly

Hi there,

I have following problems with my RS232 K2 connection:
On a desktop PC with WIN7 everything working OK, all COM ports including 
USB/COM adapter running without any issue. When I am reconnected same 
USB/COM adapter with the same cable (between K2 and adapter) to the USB 
port on laptop, no communication. Of course the driver in laptop is 
installed and from the utilities and hardware control looks all OK. USB 
ports on laptop are working (checked with USB flash). All parameters on 
the COM port are the same as on desktop PC. I am on the end of my 
knowledges now, any help?

Karel, OK2FD
