Trash in Ubuntu

My father had a strange problem. He couldn't delete few files from his Trash. First we figured out that he didn't have 'write' rights to them, even if he saved them from a mail. My first suggestion was to change permissions, but he couldn't (using Nautilus). Today I had a chance to sit in front of dad's computer, but I couldn't find where is the Trash. I decided to check if there were any similar bug report in the launchpad. I found this suggestion, which work for me (of course I need to make chmod -R +w ~/.local/share/Trash/files/*). And the point I would like to save here is that the trash in Ubuntu is in:

~/.local/share/Trash/files/

Cordless USB phone - not working with Ubuntu

This time no-success story. I bought the WP-01 VoIP Dect Cordless Handset on ebay (from shop4USB). In Product Description there was an info that it works with "Linux2.4 above". In reality it was working only partly, very partly. Indeed the only part working was sound (as normal sound card), it means I could hear and speak after /choose a number/pick up a call/ using Skype software. Anything ( ring, Keyboard and LCD) wasn't working. Phone was recognize by system and asign to USB HID module:
dmesg |grep hid [ 33.859714] usbcore: registered new interface driver hiddev [ 33.866820] hiddev96hidraw0: USB HID v1.00 Device [HID 06e6:c31c] on usb-0000:00:1f.4-2.2
I tried to make yealink module controlling phone.
rmmod ubhid modprobe yealink
But, how I expected, it didn't help. Finally, the phone USB info was/is
06e6:c31c Tiger Jet Network, Inc.

PS. The seller was OK and gave me my money back.
