Using a DB9 male to female cable to transfer USB signals?
would it be possible to transmit a USB 2 Low speed, sure. Full speed, maybe. High speed, highly unlikely. USB 3 Haha absolutely not, they need very tightly controlled differential impedance on the high speed pairs. More on reddit.com

Usb to female db9
The console port on the itself is a male db9 port. Does this mean I need a "usb to female db9" cable, because I can't actually find one. Most of them have male db9 or rj45 connectors ... Just get a db9 female/female adapter and put it between the console porr and your usb serial adapter with db9m. More on reddit.com

DB9 to RJ45 serial connect to switch - correct pinout?
This pinout worked for me: RJ45 -> DB9 RTS 1 -> 8 CTS DTR 2 -> 6 DSR TXD 3 -> 2 RXD GND 4 -> 5 GND GND 5 -> 5 GND RXD 6 -> 3 TXD DSR 7 -> 4 DTR CTS 8 -> 7 RTS IIRC, I had to leave one of the ground pins unplugged. http://i.imgur.com/O3RRKQC.jpg *Edit: Here's another picture for clarity. Also, you can push the pins back out with something like a small flathead screwdriver (~1mm). http://i.imgur.com/7hWniXb.jpg More on reddit.com
