The STM32F302 uses the USB buffer memory layout like as in st_usbfs_v2.c. But it doesn't have all the registers, e.g. USB_BCDR is used in st_usbfs_v2.c but not available in the...

Compiling in both st_usbfs_v1.o and st_usbfs_v2.o will likely result in a conflict for `st_usbfs_copy_to_pm` and `st_usbfs_copy_from_pm`.

The same exception can be trigger when trying to open a device that was disconnected (the application kept it in a variable). The behavior has now been changed. It now...

**Analysis Linux:** Linux seems to retrieve the first languages (declared in string string descriptor with index 0). **Analysis Windows:** For the Windows implementation, manufacturer and product name are retrieved using...

Thanks for the proposal. I will think about it. It sounds interesting to have more information about USB devices and make the bridge into other worlds: storage media to file...

It is impossible to say what the cause is without seeing your code and having more information about the printer. Are the 4 sent bytes data your printer understands and...

The reason a _UsbTimeoutException_ exception is thrown is probably simply because the printer does not send any data. If it is supposed to send any data after the bytes it...

This error has always been related to SPI communication. It's the first SPI interaction after start. So far it was either a wrong pin configuration or an invalid SPI mode....
