Re: RS232 Hardware Flow Control in Windows 7

The behavior it leads to is this: I have a Data-logger that uses the serial port. When the port is opened the data logger sends an identification string.

Re: USB Over-Current Condition

I believe ports 8 & 9 are the rear ones and I have nothing connected to them.

USB Over-Current Condition

Hello,
When booting in Linux Mint, I see these messages appear:

usb usb8-port1: over-current condition
usb usb8-port2: over-current condition
usb usb9-port1: over-current condition
usb usb9-port2: over-current condition

Is this a problem with the hardware?
Or is it just a warning?

As the USB power remains on I can't use this and I have tried using the Serial port e.g. RTS voltage, but it remain "Low" after shutdown from Windows. Is the...
