Trident, Subway or FastAta problem?

[platon42]

Use lower case subwayusb.device - on Amiga the file name of disk based libraries and devices MUST match the internal name of the object. Make sure the file name is in lower case.

I'm afraid I'm only the software guy. Better ask the hw guy.

Ps: The detection of the subway expansion is afair a two-steps approach. First, a read-only algorithm (that won't disturb other expansions on the clockport) makes sure that a serial ID can be read reliably, then a second test checks the actual usb controller... If either one fails, you get a -1 error.

Any spikes on the Chip-Select line or other address related wires can make the communication with the Subway unreliable. As the Clockport only has a 4 Bit address bus, there is an auto-increment mode in the controller. Random spikes will cause it to malfunction.

Good work! I'm glad you found the problem. Enjoy your subway finally
