Want to clear the situation. I'm developing some kind of audio device that uses EP1 as HID for control and EP2 for audio data. Things work ok for stm32f103 except i2s accuracy. What I'm doing with stm32f105:

1. initializing endpoint:

OTG_DEV_EP_Init(EP2_IN, OTG_DEV_EP_TYPE_ISOC, 192);

2. correcting usb headers:

#define EP_NUM (3)

/*#define EP2_IN_Callback NOP_Process*/

But in fact EP2_IN_Callback() never gets called. USB descriptors are the same as in stm32f103.

No pullup needed, and yes, the VBUS must be connected to low impedance high level (some very low R pullup/pulldowns active on this pin :| ) Or you can program the pin as high-driven pushpull.

I cannot get the VCOM working (using my own hardware).

Using KEIL compiler and a SMT32F105RC.

Has anyone made a KEIL version of the given RC1 sample (VCOM part).

The computer (Vista & XP) is not detecting a correct device.

Please help, after 5 days trying I'm out of ideas.

Must the VBUS pin be connected to the USB interface (just an 'old-style' USB connection used?

Or can I use PA9 as USART1_TX?

Do I need to connect an external pull-up tho the D+ line (in the eval board ...C this pull-up is NOT used), Is the one internal in the CPU ?

Hi STOne-32

Thanks for you and ST for providing us with a beta upfront. That helped quite a lot in meeting our ever-so-tight timescales.

I used the HID device part of the beta driver and so far so good. It was fairly easy to port my existing project to make use of the new driver.

Thanks,

Gawie
