How to remove ghost USB devices.
Contents
datasheets
standard build
- DNP EEPROM : RE1,UE1, RE2
- DNP ISP select : SS1
- The blue LEDs are too bright - MAKE RM2, RM3 - 470 ohm (corrected in 2hb)
known issues
- EEPROM lacks pull up on EECS (corrected in 2hB)
- Need 10K resistor pack for RE2 (has 1k) (corrected in 2hB)
- the ISP select should switch the power supply also. eg the ISP is connected to PORT1 power and gnd, but if there is nothing connected - the realice thinks that nothing is connected.
- will need a way to latch the present ISP selection as when the SERIAL port is close, the value can't be changed.
- also want an LED to indicate which port is selected.
ECO to fix for EEPROM
- cut trace to RE2, pin3
- run wire from RE2.3 to UE1.1
serial numbers
- 1 - assembled 10-15-09; tested both isolated serial port; ISP not programed.
- 12-9-09 : connecting to port0 causes the SC VBAT supply to blow 200mA fuse.
- has 1 ISP connector and uses ISP switch
- after addition of EEPROM - doesn't enumerate
- need to re-assembly to use 2 ISP connectors.
- CEB removed RR1,RR2 and RR3
- 2 - assembled 10-16-09;
- has 2 ISP connectors.
- after addition of EEPROM - doesn't enumerate
- CEB removed RR1,RR2 and RR3
- 3
- needs UI1 replaced
- 4
- needs UI1 replaced with IL712-1E
assembly mods
- RE2 will be 10k not 1k
- 4.7uF replaced w/10uF (due to non-availability)
