Turn off you security system and then see if it gets through
Set up another user on your computer and see if iTunes finds it then
Have a look at these articles too, they may help you out.

Currently Being ModeratedJul 20, 2010 12:24 AM (in response to Mooman_Naylor)Hi There,
I suffered the same problem as the original poster. I now have my first ever iBrick stuck in recovery mode. Short story coming please be patient.
When i got in from work last night i hooked it up to my iMac as usual and it prompted me for an update to 4.0.1 so as usual i just said yes because i have never had an issue before and shortly after the backup started it flashed up an error saying unable to update error code 21. Now every time i reconnect the iPhone it recognise's that it has to recover but does the exact same thing when it try's to do the restore. Bing!!! Error code 21. Please excuse my frustration.
I have tried most of the solutions the support page has suggested (open ports on my router, reboot mac, remove all other USB's and try another USB port) all except reinstalling iTunes becasue i didnt have time to do that last night.
Please note i have never had an issue with my new iMac or my 2 month old Iphone and i don't have any other hardware i connect my iPhone to.
I was hoping some one may be able to offer me further assistance or advice before i go down the line of contacting Apple Support direct.
Thanks for your time.

Currently Being ModeratedJul 20, 2010 3:14 AM (in response to cappo84)ITunes for mac has an update available, 9.2.1 with lots of bug fixes including syncing issues.
I would start by downloading the update using your Software update feature.
Restart your computer and see if that helps your issue.Intel C2D 2.4GHz MacBook 13"-Al (Late 2008), Mac OS X (10.6.4), iPhone 3GS iOS4.0.1 GMT+10
Currently Being ModeratedJul 20, 2010 4:39 AM (in response to actionmarker)I should apoligise, i forgot to mention that i ran software update last night after trying to restore it. But it the Software update tool said everything was up to date. Am usualy pretty quick to have everything up to date. I think when i get in tonight i will be reinstalling iTunes and trying that.
Thanks for the suggestion though.Imac 27" i7, Iphone 3gs
Currently Being ModeratedJul 20, 2010 4:56 AM (in response to cappo84)Just double check that you do have the latest, because that version is only came out yesterday.
Have you tried creating a different user on your computer and seeing if you can restore from that one? Can't remember where I saw that tip, but if you are having troubles, apple suggests using a different computer or a different user to restore. (this maybe a windows thing too though)
If you do decide to re-install iTunes, make sure that you do the complete removal procedure, which is detailed here, http://support.apple.com/kb/ht1224
