Subject: Intel ISH doesn't generate IRQ

Hi,

This is an old issue filed at [1].

Few days ago I noticed there’s a new commit 74fbc7d371d9 ("HID:  
intel-ish-hid: add MSI interrupt support”) that may solve the problem.
Unfortunately it the device in question doesn’t support MSI and MSI-X, so  
the commit doesn’t make any difference.

Please let me know what additional information I can provide.
