Robert Fisk	f51ae234c6	Fix for the previous fix. This time for sure. Previously we wrote 4 x 64 byte transactions to the downstream device. This is fast, but very occasionally the USB host silicon would bug out. Reverting to single 64 byte write transactions increases reliability at the expense of some write speed.	7 years ago
Robert Fisk	6697c9fea4	Another fix for occasional mass storage write freakouts. USB host controller sometimes incorrectly reports number of TX packets in queue.	7 years ago
Robert Fisk	b96c539088	Implemented FIFO support in Downstream host, significant speed increase! Each USB transaction passed to the driver now consists of multiple 64-byte packets. 8 packets when receiving, 4 packets when transmitting. The STM32 silicon bugs out when more than 4 packets are scheduled to write at a time :( Reads 1.0MB/sec, writes 967kB/sec, not CPU limited :)	8 years ago
