Comment 198 for bug 85488

I have usb standby problems with scanner BenQ 4300U and found this bug entry.
The workaround to run scanbuttond did not help at the first try --> the scanner lamp starts to flash. This shows me that the poll interval was still too long. So I tried to poll the scanner faster.
scanbuttond -f -p 1000 -r 10000
This helped in my case. The solution seems to be not very stable but I can scan with it. So if you still have the problem pleas try to start "scanbuttond -f -p 1000 -r 10000" in the terminal before starting xsane. After scanning you can end the running scan button daemon by pressing Ctrl+C in the terminal window.

(But there is still a question for me: "scanbuttond -h" says, that pollingdelay and retrydelay are in ms. Could that be true? It would mean the default poll delay is 333000ms=333s=nearly 6 minutes? Is poll delay meaning poll interval? Poll every 6 minutes...?)
