I observe the same problem under 7.99.39. It's been like this at least
since 7.99.36, on both i386 and amd64, but was working well under 7.99.7
on i386, at least.
I believe the manifestation of the problem on my amd64 system shows a
pattern: the USB subsystem will get hung up the second time the USB
serial device is opened, requiring a hardware forced reboot to recover.
I may be mistaken; it's behaved this way three or four times in a row
during testing with 7.99.39, but this still could be a coincidence.
I test using a small application I wrote to decode data coming in from
the Tellstick, but opening the port with kermit has the same result.
The relevant kernel output for the device:
