Bug#517051: Obtaining the ink level from EPSON Stylus D88 stopped working after upgrading to escputil 5.2

[darkbasic <darkbasic4@gmail.com>]

Package: escputil
Version: 5.2.3-2
Severity: important

If I try to obtain the ink level from my printer (EPSON Stylus D88) with escputil 5.2.3-2 I obtain

# escputil -iur /dev/usb/lp0

Cannot write to /dev/usb/lp0: Resource temporarily unavailable

(I tried also without -u)

while using the old 5.0.2-4 (the lenny one) I have no problems.
