Robert Fisk	46ecbd410d	After an epic battle, suspend/resume/wakeup is now supported. It turns out that suspend support on the STM32 USB core is buggy as heck. Host mode cannot resume after suspend, and device mode cannot receive resume or send wakeup signalling. I managed to fake resume support by keeping Downstream and our connected device running at full power, and simulating a wakeup event to the host by disconnecting/reconnecting Upstream from the host.	9 years ago

Robert Fisk	2983da24b2	Changed Upstream and Downstream SPI transfers back to DMA. DMA works correctly now, either because SPI is in 16-bit mode, or because I found all the other bugs! Doubled SPI baudrate to 10.5Mbps. Transfer speed now limited (again) by Downstream's lack of FIFO buffering in the USB host controller. Also disabled DMA transaction half-complete interrupt in stm32f4xx_hal_dma.c, as it wasn't doing anything useful.	9 years ago

Robert Fisk	d3da69eb07	Draft implementation of downstream SPI interface. Significant mods required to USB MSC class, mainly in usbd_msc_scsi.c. Currently untested!	10 years ago
