Trinket Help

[SPOD]

I have purchased a trinket 3v from one of your distributors and I am having a hard time programming it.

I use Windows 8.1 and I was following the trinket tutorial "Setting up with Arduino IDE." I chose the fast way by downloading the trinket compatible Arduino IDE for windows. When I attempt the blink program I still get the large stream of errors, as per your help page. I have also installed the driver for the trinket.

Please help. Thank you for your time.

Please post the errors you're getting. You should be able to copy and paste from the error window.

The errors are as follows plus a whole lot more:

I only followed the advice of the article and edit the following:

chip_erase_delay = 900000;

under the ATtiny85 heading to

chip_erase_delay = 400000;

Now I only have this error appear:

Binary sketch size: 832 bytes (of a 5,310 byte maximum)

avrdude: error: usbtiny_receive: usb_control_msg: sending control message failed, win error: A device attached to the system is not functioning.

(expected 4, got -5)

Sometime we see that error, but the download still succeeds.
Does your sketch work after the download? If so, you can ignore the error.
If not, try a different USB cable, try a different USB port, and/or try connecting the trinket through a self-powered USB hub.

[SPOD]

Yes, I tried a different USB, 2.0 instead of 3.0, and the program is downloading.

I still get the error, but it works.

Thank you very much for your help.
