Can use to communicate iBoot iOS devices ?

hi, please manage docs how to communicate with iboot ios. like send file, send command, etc

STM32F730 Memory descriptor fails

When connecting to an STM32F730, the usbDevice gives a descriptor string of:
"@internal Flash /0x08000000/04016Kg,0164Kg,03*128Kg\0"
for the Memory description.
In the STM device itself, the descriptor string includes a single trailing '\0' character within the length of the string, and this is interpreted by the usbDevice as a trailing "\0" (2 characters) on the end of the string, as seen above.
This then fails the SeMemoryLayoutRegex and aborts the process.
Editing the string to remove the "\0" in debug 'fixes' the problem.

So, this appears to be a failure to handle unexpected descriptor string contents as parsed by LibUsbDotNet.
I don't know if there are options for IUsbInterface to parse this differently (and just truncate the string at the zero) or if it could be stripped off in LibUsbDfu.
(Strictly speaking, the actual zero in the descriptor itself shouldn't really be there, but it is.)

Setup Nuget package

crossplatform / multitarget release

Hello, at first cool and fine work to bring dfu capability to c#.

It works in windows with zadics winusb drivers very good. In linux with rules
(SUBSYSTEM=="usb", ATTR{idVendor}=="0483", ATTR{idProduct}=="df11", MODE="0666")
the libusbdotnet can't open the dfu device and device.cs throws "The device doesn't have valid DFU interface".

I used the same arguments on both platforms, other dfu-tools like dfu-util or the stm programmer works with
user rights. For me, it seems to be a problem with libusbdotnet, but maybe you can make a workaround or fix
it.
Best regard, Martin
