USB not recognised error in STM32f103

[Vicky-S]

HI,
I bought STM32F103C8T6 today. when I connect my controller via micro USB it shows USB not recognized error. What is the problem and how to solve this?

Currently with this core, this is normal as it is not managed. USB provides power that's all.
#344 will provide this support.

ok. Then I need to buy STLINK to program this controller right?

No, you can Upload via Serial. See chapter Upload via Serial here: http://wiki.stm32duino.com/index.php?title=Uploading_a_sketch

I let you close this as answered.
USB will come with 1.5.0 core ;)

When will 1.5.0 come?

1.4.0 will come next week. Then I will handle to release an 1.5.0 with USB feature
