No option to scan 35mm rolls with 10.10.2 and a HPScanjet g4050

Question

before the necessary use of Image Capture to get access to my scanner options, i used the "original" HP software without problems, The scanner performed all the necessary work in a sequence, working in "backstage"  while other tasks were made. After the introduction or the Apple "obligation" to use Image Capture to get  scanned  results, the process worked correctly for a while, (after if i remember correctly the leopard /tiger updates...), but recently i need "again"to scan archived rolls, and  with Yosemite, NO WAY... HP updates are installed,  the scanner works for flat doc, images, picts, aso, but when the 35 mm roll scan option is set in Imag e capture /scanner options, i can choose  with the small rectangle   (35 mm pict size) a part of the 5 strips on the scanner "preview" tray, BUT id scan is asked, no results. The scanner moves very fast over all the tray, and no result  appears.
I was suggested to "un-update"  the recent updates, and use an older version of OS who "could" be still compatible with such EXCELLENT SCANNER.
Is such problem actually related to the recent update of Mac OS, or is the scanner( or my mac) infected or unadjusted correctly in some way ?
if the Apple software update produced such problem, how could that be justified ? Because all must be digital to be compatible with modern Mac's, and their design of newer OS are considewrinf scanning 35 mm archives an obsolete option  in 2015 ?
Any clue ?
Thanks

Similar problem with a Photoscanner HPscanjet 4890 : all ok for doc's pdf pictures ... but no way to scan 35mm slides with the HP soft. The preview scan is OK, as well as the thumbnails of the16 scanned slides. As soon as I start to save those slides, I got a message that the scanner couldn't write the file.
When scanning multiple slides or 35mm strips the scanner needs to write a text file to organize the separation of all the individual pictures. I saw this under SnowLeopard:the scanner writes a number of small temporary files in the root directory. Apparently, on Yosemite this is not allowed ...
My work around (from last week) :
If you have a possibility to boot up on good ol' SnowLepoard -  you can just scan your slides or strips as usual.
What i did on Yosemite :
Start the scan, on the sidebar it will show a scan with all individual pictures on it, and below all the single pictures.
Now, delete all but one of these single pictures.
Then, on the multiple view, extend the last only selected picture all over all the others, the individual one now shows you the whole assembly !
Save it (its a single file with all on it, it can grow very large - mine was 1.5 GB)
Then do the separating job manually, in Gimp i selected and saved picture after picture in individual files. After 50 or so pictures that procedure goes very fast
