I've checked the suggestions in the #upload section, but I did not find a solution for my problem.
I have two Arduino Uno boards of the same type. Whereas uploading my program to the first one works well, uploading to the other one does not.
I can read the board-Info (see attachment), but uploading the program leads to the error
"avrdude: ser_open(): can't open device "\.\COM9" (see attachment).
I am using W7 SP1 (32 Bit), latest updates included. The program just leads to a slow-blinking LED Nr. 13 (but this does not matter, since it is not uploaded).
I'm having similar issue with a arduino genuino 101 board and I haven't found a solution yet either. Tried different cables and computers but still unable to upload any sketches. I'm thinking of trying to reload the bootloader but I don't have a programmer.

You might want to go to the Arduino 101 section for this one.
Just got a 101 myself this morning and having some issues uploading myself.
Taken all day but finally got a sketch in by pressing MASTER RESET every 3 seconds whilst it was compiling to upload as recommended for another issue over there.
However, after applying some ideas written in other issues (changing the COM-Port-Nr., reinstalling the driver, ...) and also after unsuccessfully frequently pressing the RESET-button during compilation / "uploading" I assume a fault in the board (HW or SW). Iam not going to spend more time on that issue and I'll send the board back to the shop.
