Hi Matt I see your question 10-12 now: Wednesday 14-12
I am not at home for 2 days. I can test. You hear as soon as possible.

Is anyone else able to test the 18f4455 blink usb sample? On Saturday, December 10, 2022 at 1:18:39 PM UTC-5 hans wrote: Hello, I tested the sample 18f4455 Blink_hs_usb.jal. This one didn't work. Then I restarted Bert van Dam's old business and tried the same program on it. that works as it should.!!!! I have also tested ports D+ and D- (24 and 23) as inputs and those ports work as well. I now doubt whether the PIC is broken or something else is going on. regards Hans Op zaterdag 10 december 2022 om 10:30:14 UTC+1 schreef hans: Hello champs, I have reassembled everything and I can only conclude that the PIC itself (has done some things before) is defective. Unfortunately, I no longer have a PIC with USB, so I put it back in the fridge. I will have to look for another one but the market is scarce. Thanks again for your great responses. regards Hans Op zaterdag 10 december 2022 om 06:18:17 UTC+1 schreef vasile: Yep. Matt has right. 1.The clock speed is esential. 2. You will notice quite a long delay (5s or so) between plugging the pic usb and the moment when OS recognize it on pc. This depends by your computer speed and pic firmware contents. If pic clk is wrong, you will not see any usb device. After it appears, check on printer/pheripheral for your device but watch for any warnings there....

Do you have the correct clock speed? Make sure a blink sample and normal serial port is working. Try another PC. Windows should pick it up. Matt.

Same message from windows, not recognized and causing a malfunction. Pffffff/ regards Hans Op vrijdag 9 december 2022 om 18:43:24 UTC+1 schreef [email protected] <mailto:[email protected]> : Hi Hans, As Vasile already mentioned Windows 10 will detect your device as a serial (COM) port without the need of installing a separate driver. Make sure you have the USB connections right. The signals are not crossed like for USART, so D+ to D+ and D- to D-. I attached a schematic diagram based on the PIC16F1455 for your information and the USB connectors and what the signals look like. Good luck!

Download the last jal package, Rob did some modifications on USB driver, my suggestion is to use const USB_INTERRUPT_DRIVEN = TRUE The maximum speed is about 100kbps.
