which type of usb library patches you want to submit?

Is it any official patch for STM32 USB host/device lib?

I have written usb bluetooth example app based on ST usb libs and btstack project, including usb host mode bluetooth class interface to btstack.

In the course of debugging I fixed several issues in usb library. These are quick fixes (may they need more careful approach) but the issues are real and my app didn't work until them applied. So, the second answer is: no, they are not, but it would be nice to ;)

Oh thts good.

If it's not that bulky you can release it on e2e itself. Other wise you can contact regional FAE to know where to release.

Contact regional FAE -- wow, it is supposed to be easy, no? ;)

Anyway, the patch (against stm32f4 fw 1.1.0) is attached. Couple comments: USBH_InterruptSendData() prototype should probably be modified the same way as USBH_InterruptReceiveData(), anyway, BT HCI needs receiving events greater than 256 bytes. USB_OTG_ResetPort_I() is not included, be it's definite that calling 200ms+ delay from ISR should be frowned upon. And couple more fixes. My greatest concern is actually usb toggling bits, which without doubt are fixed only partially. ________________ Attachments : stm32f4discovery_fw.diff : https://st--c.eu10.content.force.com/sfc/dist/version/download/?oid=00Db0000000YtG6&ids=0680X000006I0aq&d=%2Fa%2F0X0000000bb2%2FsDIqRQvxldXhZ39NScG2XJs78ZrtB.UldHqjjLXcPd4&asPdf=false

Hello Bezymenko,

Are you willing to share your efforts/experiences with implementing bluetooth on ST processor? Thanks in advance.
