1.0 relesed binary of Jan 8 works, compiled version of Jan 28 does not work

[tosiara]

There is a binary release v.1.0 of 2019-01-08: https://github.com/wosk/stm32-vserprog-lpc/releases/download/v1.0/stm32-vserprog-lpc.hex
I have flashed this version into STM32 "blue pill" STM32F103C8T6 and it seems to boot fine and initialize USB serial:

[23265.590005] usb 1-1.2: new full-speed USB device number 32 using ehci-pci
[23265.700783] usb 1-1.2: New USB device found, idVendor=0483, idProduct=5711

[23265.779150] usbcore: registered new interface driver cdc_acm
[23265.779151] cdc_acm: USB Abstract Control Model driver for USB modems and ISDN adapters

But if I try to compile and flash from the sources (latest master of 2018-01-28 1996dd1), the board does not initialize correctly Usb serial:

[23449.341587] usb 1-1.2: new full-speed USB device number 35 using ehci-pci
[23454.492855] usb 1-1.2: unable to read config index 0 descriptor/start: -110

Do you still have source snapshot of Jan 8?
