fix(legacy): Replace magic numbers with USB_PACKET_SIZE and MSG_HEADER_SIZE. 2021-02-09 18:07:48 +00:00			`#define USB_PACKET_SIZE 64`

import v1.0.0 2014-04-29 12:26:51 +00:00			`void usbInit(void);`
			`void usbPoll(void);`
			`void usbReconnect(void);`
Poll USB during BIP39 derivation. This patch adds calls to usbPoll in the progress callback. This should address #98. We call usbDelay instead of Poll, to call usbd_poll several times. Otherwise it would only handle one event instead of handling all events that were pending so far. The ugly magic number 5 is a guess. Note that we also need to set usbTiny, so that we don't recursively process messages. Since we don't know whether usbTiny is set, we need to store the old value (especially true for u2f). This fix also relies on another fix in libopencm3. 2016-07-07 16:37:37 +00:00			`char usbTiny(char set);`
timer: Use Cortex-M3 SysTick timers Removed `usbDelay(uint32_t cycles)`, added `usbSleep(uint32_t millis)` The same method signature could cause silent code breakage at runtime, as opposed to noisy code breakage at compile time which is the better kind. 2016-11-17 19:07:41 +00:00			`void usbSleep(uint32_t millis);`
fix(legacy): prevent handling RebootToBootloader recursing by flushing USB write 2021-12-06 21:08:20 +00:00			`void usbFlush(uint32_t millis);`
