Hi I'm trying to build my own custom arduino board. The FT232rl doesn't want to accept the address given to it. I've wired in all the gnd and vcc wires. Including the gnd wire for the usb port. I'm getting this error in my dmesg
[23289.780022] usb 4-3: new full speed USB device using ohci_hcd and address 75 [23290.201047] usb 4-3: device not accepting address 75, error -62 [23290.370021] usb 4-3: new full speed USB device using ohci_hcd and address 76 [23290.790020] usb 4-3: device not accepting address 76, error -62 [23290.790030] hub 4-0:1.0: unable to enumerate USB device on port 3
I've wired pin 2 of the usb port (D-) to pin16 and pin 3 to pin 15. Am I not correct in saying the FT232RL has a build in usb transceiver so therefore it should be able to register as full speed device by itself? I have a ttl converter using the same chip that registers as soon as I plug it in.
According to my scope the chip is oscillating at 38MHZ so I can only assume I didn't damage it when I was soldering it. I have to admit this is the first ssop I've soldered.
Wired the same except I've not wired in the tx/rx. I've also wired the test pin to gnd because the DS told me to. Windows detects as unknown device but in device manage it said it's been disabled because the device reported issues.
